A 0.240 kg hockey puck has a velocity of 1.70 m/s toward the east (the +x direction) as it slides over the frictionless surface of a frozen lake. What are the (a) magnitude and (b) direction of the average force that must act on the puck during a 0.460 s interval to change its velocity to 6.20 m/s west? What are the (c) magnitude and (d) direction of the average force that must act on the puck during a 0.460 s interval to change its velocity to 6.20 m/s south? Give your directions as positive (counterclockwise) angles measured from the +x direction.

Three skydivers are plummeting earthward. They are initially holding onto each other, but then push apart. Two skydivers of mass 70 and 80 kg gain horizontal velocities of 1.2 m/s north and 1.4 m/s southeast, respectively. What is the horizontal velocity of the third skydiver, whose mass is 55 kg?
A baseball (m = 152 g) approaches a bat horizontally at a speed of 43.6 m/s (97.6 mi/h) and is hit straight back at a speed of 53.8 m/s (120 mi/h). If the ball is in contact with the bat for a time of 1.03 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.

A 0.065-kg tennis ball moving to the right with a speed of 15 m/s is struck by a tennis racket, causing it to move to the left with a speed of 15 m/s. If the ball remains in contact with the racquet for 0.020 s, what is the magnitude of the average force experienced by the ball?
A baseball (m = 148 g) approaches a bat horizontally at a speed of 40.7 m/s (91.1 mi/h) and is hit straight back at a speed of 51.6 m/s (115 mi/h). If the ball is in contact with the bat for a time of 1.45 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.
A baseball (m = 149 g) approaches a bat horizontally at a speed of 40.3 m/s (90 mi/h) and is hit straight back at a speed of 50.0 m/s (112 mi/h). If the ball is in contact with the bat for a time of 1.10 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the ball, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction. N
An open train car, with a mass of 2050 kg, coasts along a horizontal track at the speed 2.792.79 m/s. The car passes under a loading chute and, as it does so, gravel falls vertically into it for 2.792.79 s at the rate of 475 kg/s. What is the car's speed vf after the loading is completed? Ignore rolling friction.
A stone of mass m = 1.55 kg is dropped from a height of h = 3.9 m into a pool of water. At a time of t = 1.9 s after hitting the surface of the water, the stone's velocity has decreased by 50%. What is the magnitude of the average force the stone experiences, in newtons, during the time t?
A car with mass mc=1270kg is traveling west through an intersection with a speed of vc=14.41m/s when a truck of mass mt=1740kg traveling south at vt=6.63m/s fails to yield. The vehicles collide, they stick together, and they slide on the asphalt which has a coefficient of kinetic friction of μk=0.500. Associate the positive x direction with east and the positive y direction with north. a. Using the symbols provided in the palette below as opposed to their numeric equivalents, enter an expression, in Cartesian unit-vector notation, for the velocity of the vehicles immediately after the collision, as they begin to slide as a composite object. b. How far, in meters, will the vehicles slide after the collision?
A ball of mass m = 1.55 kg is released from a height of h = 2.8 m into a tank of water. At a time of t = 1.08 s after hitting the surface of the water, the ball's velocity has decreased by 50%. 1) What is the magnitude of the average force the ball experiences, in newtons, during the time t?
A 0.576-kg ball, initially moving with a speed of 2.93 m/s, bounces off a wall and then moves with a speed magnitude half of its original directed in the opposite direction. If the ball is in contact with the wall for 5.2 ms, what is the magnitude of the average force that the wall exerts on the ball? Express your answer in two decimal places, in Newtons.
A tall man walking at 1.10 m/s accidentally bumps his head of mass 3.07 kg on a steel doorjamb. His head stops in 0.019 s. What is the magnitude of the average force exerted by the doorjamb on the man's head?
A hockey player with a mass of M = 72 kg, standing on ice, pushes a plate with a mass of m = 0.5 kg in a horizontal direction at a speed of v = 30 m / s, which causes him to start moving in the opposite direction. After how long it stops if the coefficient of friction between the skates and the iceis kt = 0.02 and by how much does it move?
