| A ball rolls down a ramp for 15 seconds. If the initial velocity of the ball was 0.8 m/sec and the final velocity was 7 m/sec, what was the acceleration of the ball ? | 0.413 m/s² |
Is there a maximum falling speed?
The maximum speed is called terminal velocity. The terminal velocity of a skydiver in a free-fall position, where they’re falling with their belly towards the Earth is about 195 km/h (122 mph). But they can increase their speed tremendously by orienting their head towards the Earth – diving towards the ground.
How fast is faster than the speed of light?
The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.
What is the average speed of a walker who walks 500 m in 400 seconds?
1.25m/sec

What is the speed of a jet plane that flies 70 km in 9 hours in km HR?
Answer. To find : Speed of jet. =>S = 7.778 km/hr.
How fast do planes go?
How fast do commercial passenger jets fly? A typical commercial passenger jet cruises at a speed of about 400 – 500 knots which is around 460 – 575 mph. Generally speaking, the higher the aircraft flies, the faster it can travel. It cruises at this speed at a height of about 36,000ft.
How many miles can you see at 30000 feet?
211 miles
How far can pilots see?
So, assuming that the pilot’s eye enable him/her perfect human vision, with good lightning and sun position, aircraft color is distinguable enough on the sky as a background, I think it’s safe to say the same distance you can spot it on the ground with perfect conditions. About 4–6 km.
What is the air temperature at 35000 feet?
How cold is it up there? The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.
Can you see a plane flying at 30 000 feet?
So, at 10,000 feet you can see 122 miles, at 30,000 feet you can see 211 miles, and at 40,000 feet you can see 244 miles. If you look up into space you are looking through about 62 miles of atmosphere, at 35,000 feet you will be looking through almost 230 miles of atmosphere to see the horizon.
Are planes checked before every flight?
Before each and every flight, one of the pilots will conduct a preflight check to evaluate whether the aircraft is airworthy and fit to fly. This is done before every flight. Every.
What happens if a plane flies too high?
When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
How Low Can planes fly over my house?
The regulations usually require that pilots fly no lower than 1000 feet over built-up areas, or 500 feet over any other area, and we may investigate low flying incidents. You can report a low-flying aircraft by completing a report a low flying aircraft form, along with any information to support your complaint.
Why are planes flying so low now?
Why are the airplanes flying so low over my house? Aircraft are limited in the direction they fly because they must land into the wind. Therefore, the flexibility of air traffic is dependant on the wind patterns of the day or, even, the hour, as winds can change rapidly.
Why do planes fly low at night?
FAA recommends general aviation aircraft to stay below 5,000 ft at night time. But one of my friends claimed the reason why we are supposed to fly at a lower altitude to prevent from hypoxia is that at night there is higher pressure near the ground which makes fewer air molecules at high altitude at night than daytime.
What is the lowest a helicopter can fly legally?
500 feet
Is flying at night more dangerous?
Accident statistics suggest that flying by night accounts for about 10% of the general aviation accidents, but 30% of the fatalities. That suggests night flying must be inherently more dangerous than aviating when the sun is up.
Do pilots sleep on flights?
The simple answer is yes, pilots do and are allowed to sleep during flight but there are strict rules controlling this practice. Needless to say, at least one pilot must be awake and at the controls at all times. Controlled or bunk rest is more common on long haul flights that are scheduled to operate overnight.
Is it better to fly in the morning or at night?
Studies have shown that early morning flights are less likely to be delayed than those in the afternoon and evening. The good news doesn’t stop there: Airlines often sell their first flight of the morning cheaper than those later in the day, simply because most people would rather sleep, according to FareCompare.
What are the least crowded times to fly?
The least busiest time to fly is mid-afternoon. It is more expensive than early morning or late evening. It would be okay if she didn’t have connecting flights or absolutely had to be somewhere at a specific time.
Is landing or takeoff more dangerous?
Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.
Which country has the most airplane crashes?
