A basketball player drops a 0.60-kg basketball vertically so that it is traveling at 6.3 m/s when it reaches the floor. The ball rebounds upward at a speed of 4.7 m/s.
B.) Determine the average net force that the floor exerts on the ball if the collision lasts 0.12 s.
Express your answer to two significant figures and include the appropriate units.

Average force
F = m ( vf - vi ) t
= ( 0.6 kg ) (6.3 m/s - 4.7 m/s ) / 0.12
=8 kg .m/s^2

A basketball player drops a 0.60 kg basketball vertically so that it is traveling 6.0 m/s when it reaches the floor. The ball rebounds upward at a speed of 4.2 m/s. (a) Determine the magnitude and direction of the ball’s change in momentum. (b) Determine the average net force that the floor exerts on the ball if the collision lasts 0.12s.
To make a bounce pass, a player throws a 0.60 kg basketball toward the floor. The ball hits the floor with a speed of 6.5 m/s at an angle of 82 degrees from the vertical. If the ball rebounds with the same speed and angle, what was the impulse delivered to it by the floor?
A 55-kg soccer player jumps vertically upwards and heads the 0.45-kg ball as it is descending vertically with a speed of 23 m/s. (a) If the player was moving upward with a speed of 4.0 m/s just before impact, what will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic?(b) If the ball is in contact with the player's head for 23 ms, what is the average acceleration...
A 88.0 kg soccer player jumps vertically upwards and heads the 0.45 kg ball as it is descending vertically with a speed of 23.0 m/s. If the player was moving upward with a speed of 4.20 m/s just before impact. (d) What will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic? (Note that the force of gravity may be ignored during the brief collision time.) (e) If...
A 1.2 kg ball drops vertically onto a floor from a height of 32 m, and rebounds with an initial speed of 10 m/s. (a) What impulse acts on the ball during the contact? (b) If the ball is in contact with the floor for 0.020 s, what is the magnitude of the average force on the floor from by the ball? Neglect air resistance.

A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that mall 0.390 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? (b) If the ball is in contact with the floor for 0.0400 seconds, what is the average force (in N) the floor exerts on the ball?
A basketball player makes a jump shot. The 0.606 kg ball is released at a height of 2.09 m above the floor with a speed of 7.23 m/s. The ball goes through the net 3.10 m above the floor at a speed of 4.10 m/s. What is the work done on the ball by air resistance, a nonconservative force?
A basketball player makes a jump shot. The 0.613 kg ball is released at a height of 1.86 m above the floor with a speed of 7.08 m/s. The ball goes through the net 3.10 m above the floor at a speed of 4.29 m/s. What is the work done on the ball by air resistance, a nonconservative force?
A basketball player makes a jump shot. The 0.650 kg ball is released at a height of 2.10 m above the floor with a speed of 7.40 m/s. The ball goes through the net 3.10 m above the floor at a speed of 4.20 m/s. What is the work done on the ball by air resistance, a nonconservative force
