How many seconds does it take to reach maximum height?
It takes two seconds to reach the maximum height of 144 feet. An object is launched from ground level directly upward at 39.2 m/s.
How do you find the maximum height of a ball thrown up?
We know the value of g in SI is 9.8 m/second square. So just for example, if a ball is thrown vertically upwards with 98 m/s velocity, then to reach the maximum height it will take = 98/9.8 =10 seconds.
How long does it take something to hit the ground calculator?
Measure the distance the object will fall in feet with a ruler or measuring tape. Divide the falling distance by 16. For example, if the object will fall 128 feet, divide 128 by 16 to get 8. Calculate the square root of the Step 2 result to find the time it takes the object to fall in seconds.
How many seconds will the object hit the ground?
1 Expert Answer Since we want to know how much time elapsed since the object was launched until it ht the ground. At the ground, the height is 0. The object hits the ground 5 seconds after it is launched.
How high above the ground does the ball go?
Therefore, at maximum altitude the velocity of the ball must be zero. Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is: Answer: 0 m/s….Objects Launched Upward.

| a | -9.8 m/s2 |
| t | 0.40 s |
What is the acceleration of the ball at the instant that it reaches its maximum height?
Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is: Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero….Objects Launched Upward.

| a | -9.8 m/s2 |
| t | 0.40 s |
Does the ball clear the net?
As this distance is more than the distance of net, so it clears the net. Let the vertical distance traveled by the ball in time t’ is y’. So, it clears the net which is 1 m high.
What is the initial velocity of a ball that is thrown upwards?
If you are measuring positive upwards (by taking the initial velocity to be +16.1) the acceleration of gravity is negative.
How do you find velocity with mass and height?
Finding one unknown in the mometum equation. Enter 1,150 in the “velocity” box and choose feet per second from its menu. Energy = mgh Where m is the mass, g is the acceleration due to gravity (9.8m/s^2) and h is the height.
