A ball is dropped from a height h. Another ball is launched vertically . The two balls meet at h/2. What is the expression of v1 launched in terms of t?

A ball is dropped from rest at a height h. Directly below on the ground, a second ball is simultaneously t thrown upwards with a speed of vc. The two balls collide at the moment that the second ball is instantaneously at rest. (They collide when the second ball is at its maximum height.) What is the height of the collision? At what time does the collision occur if both balls' motion stated at t = 0 s?
2) A ball is dropped from rest at a height H. At height h (below H) the ball bounces off a surface with no loss in speed. The surface is tilted at 45°, so the ball bounces off horizon- tally. Derive an expression for the distance the ball travels in the horizontal direction. Plot the distance traveled in the horizontal direction as a function of h where h varies between 0 and H. Nest dropped from H sorface (6 at...
please explain the answer 2) A ball is dropped from rest at a height H. At height h (below H) the ball bounces off a surface with no loss in speed. The surface is tilted at 45°, so the ball bounces off horizon- tally. Derive an expression for the distance the ball travels in the horizontal direction. Plot the distance traveled in the horizontal direction as a function of h where h varies between O and H. 3) Imagine an...
Consider a ball thrown from a cliff and another dropped vertically at the same time. The ball to reach the bottom first will be?
A tennis ball is dropped from the top of a tall building of height H. It takes time t for the ball to reach the ground. At t/2 the ball has fallen through a distance: [a] equal to H/2 [b] less than H/2 [c] more than H/2.
(a) A ball is dropped from rest from an initial height h above the floor. It then bounces several times. Draw graphs the position y(e), velocity v, (e) and acceleration ay () of the ball for two complete bounces (hitting the ground t for py Ct) ay (t) (b) If the ball is released from rest at a height h the ground? 1.50 m above the floor, how fast is the ball moving when it reach (c) If the ball...
one-dimensional movement exercise: Two balls are dropped in a vacuum from the same height, but at different times; The second ball hits the ground 1.35 seconds after the first hits the ground. A. from the above information, deduce an expression that allows you to find the difference between your heights (∆h = h2-h1)
2. A ball is dropped from the top of a 20 m building at the same time that another ball is thrown upward from a height of 2 m above the ground. If the two balls pass on an other at the height of 10 m, determine the speed at which the second ball was thrown upward Answer | 12.6 m/s.
5. A ball is dropped from rest from the top of a building of height h 100.25 m friction, find (a) How long does it take the ball to hit the ground? (b) What speed (b) What speed does the ball travel the instant before it hits the ground?
You throw a ball vertically at a height H. What height does the ball have to reach for it to spend twice as long in the air? (Note: you need to get an equation)
