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 ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m
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.
After falling from rest at a height of 32.2 m, a 0.438 kg ball rebounds upward, reaching a height of 20.5 m. If the contact between ball and ground lasted 1.76 ms, what average force was exerted on the ball? (In N)
A 1.2 kg ball drops vertically onto afloor, hitting with a speed of 20 m/s.It rebounds with an initial speed of 10 m/s. (a) What impulse acts on the ball during thecontact? kg·m/s (b) If the ball is in contact with the floor for 0.020 s, what is the average force exerted on thefloor? N
After falling from rest at a height of 34.5 m, a 0.468 kg ball rebounds upward, reaching a height of 23.7 m. If the contact between ball and ground lasted 1.96 ms, what average force was exerted on the ball?
2) A 2 kg ball is dropped and hits the ground at 10 m/s. It rebounds with 80% of its Energy. Calculate the impulse. If the ball is in contact with the ground for.005 sec, find the average force exerted on the ball.
steel ball with a mass of 40.0g is dropped from a height of 2.00 m onto a horizontal steel slab. The ball rebounds to a height of 1.60m. A) Calculate the impulse delivered on the ball during the impact. B) If the ball is in contact with the slab for 2 ms find the average force on the ball during the impact?
J, A falling 0.1 kg ball has a speed of 7.0 m/s just before it hits the floor and an upward speed of 5 0 ms immediately after it rebounds. The ball is in contact with the floor for 0.01 s. What is the magnitude (in N) of the average force exerted by the floor on the ball?
A 190 g ball is dropped from a height of 2.2 m, bounces on a hard floor, and rebounds to a height of 1.1 m. The figure(Figure 1) shows the impulse received from the floor. Part AWhat maximum force does the floor exert on the ball? Express your answer to two significant figures and include the appropriate units.
A basketball of mass m = 630 g rolls off the hoop's rim, falls from a height of 3.35 m to the court's floor, and then bounces up to a height of 1.25 m. (Assume up is positive. Indicate the direction with the sign of your answers.) (a) What are the magnitude and direction of the impulse delivered to the basketball by the floor? kg · m/s (b) If the ball is in contact with the floor for 0.165 s,...
After falling from rest from a height of 30m a 0.50kg ball rebounds upward, reaching a height of 20m. If the contact between ball nd ground lasted 2.0ms what average force was exerted on the ball?
