A ball dropped from a descending hot-air balloon at 15 m height bounces off the ground. Use motion equations to find when the ball hits the ground, determine the balloon's height at impact, and calculate the ball's rebound velocity.
A ball is thrown vertically upward at 20 m·s⁻¹ from a building roof. Using a velocity-time graph, find the acceleration, time to reach maximum height, maximum height above the building, impact speed after 5 seconds, and the building height.
Ball A is dropped from 15.2 m height. One second later, ball B is projected upward and both strike the ground simultaneously. Calculate time for A's descent, B's launch velocity, and draw position-time graphs for both motions.
A dropped ball bounces multiple times with motion shown on a velocity-time graph. Determine whether the ball is a projectile, describe motion between specific points, find bounce count, and calculate the initial drop height and maximum rebound height.
A 250 g ball is thrown upward from a 52.5 m high building, reaching 10 m above the launch point before falling and bouncing. Using a velocity-time graph, find the time when the ball reaches ground level, impact velocity, and the force exerted during contact.
A 0.5 kg ball dropped from 1.2 m height bounces to 0.8 m on a floor exerting 50 N force. Calculate impact velocity, fall time, rebound speed, floor contact duration, and sketch the complete position-time graph.
A hot-air balloon rises at constant speed. Stone A is dropped from 200 m and strikes ground at 62.68 m·s⁻¹. Stone B is released 5 seconds later. Calculate balloon speed, stone A's fall time, and distance between balloon and stone B when A hits ground.
A ball falls distance h from A to B in time t, then falls distance 8h from B to ground in 2 seconds. Show t equals 1 second, then calculate speed at ground level and heights of points A and B.
A 0.3 kg ball thrown upward from a 45 m building hits a balcony 12 m high at 29.36 m·s⁻¹, bounces at 13.77 m·s⁻¹, and reaches ground after 8.2 seconds. Find the initial upward velocity, final impact speed, and the net force during collision.
Ball A is projected at 20 m·s⁻¹ and passes point P at 6.87 m·s⁻¹ on descent. When A reaches P, ball B launches upward. They meet at Q, 8 m above ground. Find time to P, its height, B's launch speed, and sketch position-time graphs.
