An 70 kg basketball player lands from a jump and tries to stop her forward motion or momentum. The normal contact force exerted by the floor on her shoes is 2800 N. The frictional force exerted by the floor on her shoes is 800 N and this force acts posteriorly on the player. There was minimal medial-lateral force during the landing and so this component of the ground reaction force can be ignored. What is the resultant ground reaction force exerted by the floor on the basketball player's shoes? How many times greater than the player's body weight is this resultant ground reaction force calculated in part a)?

A person jumps then leaves the floor with a velocity of 1.20 m/s upward. If the person is in contact with the floor for 0.280s during the jump. What is the net force exerted by the floor on the person? The mass of the person is 80.0 kg.
A person jumps then leaves the floor with a velocity of 1.20 m/s upward. If the person is in contact with the floor for 0.280 s during the jump, what is the net force exerted by the floor on the person? The mass of the person is 80.0-kg. Your answer
A 53.8-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of -2.10 m/s. Her hands are in contact with the wall for 0.550 s. Ignore friction and wind resistance. Find the average force she exerts on the wall (which has the same magnitude, but opposite direction, as the force that the wall applies to her). Note that this force has direction, which you should indicate with the sign of your answer. Number i Save for Later Units Attempts: 0 of 3 used Submit Answer
From a resting squatted position, a volleyball player (mass = 67 kg) pushes against the ground and accelerates at the rate of 10 m/s² for 0.3 s. What is the average ground reaction force acting on the volleyball player? You are allowed a margin of error of 5 N.
You bring a small remote controlled boat with a mass of 2.2kg to a small pond to rest it out. Starting from rest, you run the boat at full throttle for a little while. After the boat has traveled a distance of 11.8 meters, it is traveling with a speed of 7.5 m/s. If the forward force of thrust acting on the boat is 12.0 N, determine the magnitude of the backward force of "water resistance" acting on the boat.
A baseball catcher is catching a fastball that is thrown at 43 m/s (96 mi/h) by the pitcher. If the mass of the ball is 0.15 kg and if the catcher moves his mitt backward toward his body by 8.0 cm as the ball lands in the glove, what is the magnitude of the average force acting on the catcher's mitt? Estimate the time interval required for the catcher to move his hands.
Helicopter drops a 0.30 kg copper ball onto a steel plate. The ball's velocity just before impact and after are 4.5 m/s and 4.2 m/s, respectively. If the ball is in contact with the plate for 0.030 s, what is the magnitude of the average force that the ball exerts on the plate during impact?

A force of magnitude 11.6N pushes a block of mass 2m which in turn pushes a block of mass m. The blocks are accelerated across a horizontal, frictionless surfac. What is the magnitude of the force that the smaller block exerts on the larger block?
A 54.9-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of -1.93 m/s. Her hands are in contact with the wall for 1.09 s. Ignore friction and wind resistance. Find the average force she exerts on the wall (which has the same magnitude, but opposite direction, as the force that the wall applies to her). Note that this force has direction, which you should indicate with the sign of your answer. Number -9.72 Units

A tennis ball is flying east towards the wall with a speed of 41.3 m/s. After bounced against the wall, it's flying west with a speed of 26.3 m/s. If the mass of the ball is 0.1 kg, and the time of collision with the wall is 0.099 seconds, what is the magnitude of the force on the wall during this process in unit of Newton?
