A constant horizontal force F = 200 N is applied for a time 0.1 s by a kick to a soccer ball of mass m=0.4 kg. If the ball was initially traveling toward the player at 20 m/s, what is the speed as it leaves her foot traveling in the opposite direction?  Choose the correct answer. 50 m/s 20 m/s 10 m/s 30 m/s 70 m/s

As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 21.5 m/s. In the process, he moves his hand through a distance of 1.45 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed. MY NOTES ASK YOUR TEACHER

A 0.2 kg ball is caught in a 0.5 kg glove.  The ball had been moving at 8.0 m/s and it required 5.0 N of force to stop it.  What was the force on the glove?

Dr. Jekyll (m = 70kg) is riding a skateboard when he realizes the cranberry juice he’s drinking is sweetened with artificial sweetener and turns into Mr. Hyde (m = 155kg). If Dr. Jekyll was initially moving at 6.5m/s, what is Mr. Hyde’s speed? (assume no external forces act)

An object of mass 12.9 kg enters a rough floor with speed of 10.1 m/s. The coefficient of friction between the floor and the object is 0.30 and the object moves 2.07 m before returning to a smooth surface (frictionless). What is the velocity of the object once it returns to the smooth surface?

Consider a tennis ball of mass 0.040 kg making contact with a racquet at 23.7 m/s for 1.30 ms. If the return speed (assume 1-D motion) is 22.4 m/s, calculate the magnitude of the average force on the ball by the racquet. 0.900 x 10³ N O 1.260 x 10³ N 1.245 x 10³ N O 2.170 x 10³ N O 1.420 x 10³ N

Hello, can you please help me with this physics question? A ball with a mass of 0.17 kg is bounced off a tenis court. Before hiting the ground, the ball is moving at a velocity of (1.4, -8.5)m/s. If the ground exerts a force of 203 N acting upward for a time of 0.0125s, what is the final velocity of the ball leaving the ground of the tenis court? (the y value is positive in the upward direction)

A 0.697 kg football is thrown upward with an initial speed of 49.7 m/s.  Neglecting wind resistance, what is the force on the ball when it reaches half its maximum height? Use g=9.8 m/s

Starting from rest, a 30.6 kg child rides a 8.50 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 6.4 m/s. If the slope makes an angle of 15.1° with respect to the horizontal, how far along the hill did she slide on her sled?

A person catches a ball with a mass of 145 g dropped from a height of 60.0 m above his glove. His hand stops the ball in 0.0100 s. What is the force exerted by his glove on the ball? Assume the ball slows down with constant acceleration.
