Answer to: A ball is thrown straight up into the air with a velocity of +20.5 m/s. Find the velocity of the ball after 2.5 s. By signing up, you'll...
What is the maximum height the ball reaches if the ball is assumed to leave from the ground?A ball is thrown straight upward in the air at a speed of 11.4 m/s. Ignore air resistance. What is the maximum height the ball will reach? (in m)...
AAns: A Before hitting and after hitting ceiling, the ball is under free fall, with a constant downward acceleration of 9.81 ,where straight downward diagonal lines are expected. During the collision with the ceiling, the downward acceleration is greater than as the ceiling, in addition to the...
