- The basketball bounces straight back up off the ground and reaches a maximum height of 4.00m. a)With what speed did the ball leave the ground? (It is perfectly natural for this to be less than the speed it had before it hit the ground.) The basketball hoop is 3.05 m above the ground. The ball will pass the position of the hoop twice –once on the way up and a second time on the way down. b)Determine the ball's velocity (magnitude and direction) as it reaches the height of the hoop on its way down.arrow_forwardA rock is thrown vertically upward with a speed of 13.0 m/sm/s from the roof of a building that is 70.0 mm above the ground.

The beanbag initially is moving with a speed of 1.21 m/s directly up the ramp. It stops at a displacement 0.35m from where it was initially, and then slides back down 1. How does the magnitude of the acceleration of the bean bag on the wayup compare to the acceleration of the beanbag on the way down? Explainyour reasoning.2.

- rocket, on an unknown planet, launches straight upward. Starting from rest, the rocket accelerates until it reaches 25 m/s then maintains that velocity until its boosters shut off. It eventually falls back to the planet. ASSUME: Starting at t = 0, the rocket accelerates upwards a total distance of 10 m, where it reaches an instantaneous velocity of 25 m/s The moment it reaches an instantaneous velocity of 25 m/s, it travels 30 m upward at a constant speed, then the engines cut off. The moment the engines cut off: the rocket is in free fall From the time it initially launches (t = 0) to the time it lands back on the planet is 7 s The acceleration due to gravity is constant on this planet. HOWEVER you may not assume g = 10 m/s2 Air resistance is negligible DETERMINE: The acceleration due to gravity on this planetarrow_forwardYou drop an object from rest (initial velocity = 0) from a height of 6.8 metres. What is the final speed of the object as it hits the floor? (Speed is a magnitude and so must be a positive value). Assume the magnitude of the acceleration due to gravity g = 9.8 m/s2.

- A ball is projected upward at time t = 0.0 s, from a point on a roof 10 m above the ground. The ball rises, then falls and strikes the ground. The initial velocity of the ball is 58.5 m/s. Consider all quantities as positive in the upward direction. At time 1-5.97 s, the velocity of the ball is closest to: 12 m/s Ozero O-175 m/s O +12 m/s O +175 m/sarrow_forwardA brick is dropped (zero initial speed) from the roof of abuilding. The brick strikes the ground in 1.90 s. You may ignore airresistance, so the brick is in free fall.
