How do you find velocity in meters per second?
How to calculate velocity – speed vs velocity
- Change minutes into seconds (so that the final result would be in meters per second). 3 minutes = 3 * 60 = 180 seconds ,
- Divide the distance by time: velocity = 500 / 180 = 2.77 m/s .

| 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 |
What is the speed of a cheetah that travels 112.0 meters in 4.0 seconds?
28 meters per second
How do you find velocity with speed?
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
Can we add speed with velocity?
If there is an increase in speed, or change in direction, or both, then the object has a changing velocity and is said to be accelerating. Therefore, simply “50 KM/ph” is a scalar, and “50 KM/ph North” is a vector. Therefore there is no question of “adding speed with velocity”.
How do you calculate speed?
Google Maps can tell you your speed, it has an inbuild speedometer, which is only currently for Android users. It is on by default, but to make sure if it is on, go to settings → navigation settings, and under the driving options menu there will be a slider for it.
How does distance affect speed?
“Faster” means either “farther” (greater distance) or “sooner” (less time). Doubling one’s speed would mean doubling one’s distance traveled in a given amount of time. Doubling one’s speed would also mean halving the time required to travel a given distance.
Does distance depend on speed?
How Does Speed Affect Stoping Distances? The faster an object is moving, the longer the distance it takes to stop. If a vehicle’s speed doubles, it needs about 4X’s the distance to stop. If a vehicle’s speed triples, it needs up to 9X’s the distance to stop.
Are speed and distance directly proportional?
– When time is constant, then speed is directly proportional to distance. – When the distance is constant, then speed is inversely proportional to time.
How does speed affect time?
Einstein’s theory of special relativity says that time slows down or speeds up depending on how fast you move relative to something else. Approaching the speed of light, a person inside a spaceship would age much slower than his twin at home. Also, under Einstein’s theory of general relativity, gravity can bend time.
Does time exist inside a black hole?
For outside observers, a black hole is one solidary element, and there is no proper time inside the black hole, but there is only the observed coordinate time according to our spacetime coordinates.
Are we all connected?
From a neuroscience perspective, we are all connected brain to brain and cell to cell. By maintaining a self-awareness of our own thoughts, feelings and actions, we can choose to impact those around us, and thus our organizational culture, in very positive or negative ways.
