A tennis ball machine holds 200 balls and has a mass of 36.0 kg when empty. Each tennis ball has a mass of 57.0 g. A coach has set the machine to launch balls horizontally with a speed of 53.0 m/s.He forgot to set the brakes on the machine. If friction between the machine and the court is negligible and all 200 balls are launched, what is the final speed of the machine?

A coach has set the machine in Problem 49 to launch balls horizontally with a speed of 52.0 m/s at a rate of one ball every 1.50 s. He forgot to set the brake on the machine. If the coefficient of rolling friction between the machine and the court is 0.00300 and all 200 balls are launched out, what is the maximum speed of the machine? (Compare your result with that of Problem 49.) Problem 49 A tennis ball machine...

[2] In a pinball machine, a ball of mass 70 g 0.07 kg) is launched up an incline by a spring. Assume the spring has a force constant of k = 1202and that the board the ball is launched onto is inclined at 10° from the horizontal. (a) If the spring is compressed by 4 cm (.04 m), to what height does the ball go above its launching point? (Ignore friction and any energy taken...

2. Two steel balls are colliding elastically. Ball 1 has a mass of 1.20 kg and is moving 3.00 m/s at an angle of 45 degrees measured from the positive X-axis before the collision. Ball 2 has a mass of 1.50 kg and is moving 2.50 m/s at an angle of 60 degrees above the negative X- axis before the collision. Assume the balls hit squarely without a glancing blow so the balls can roll in the direction calculated normally....

Q1 A small object with a momentum of magnitude 2.71 kg m/s approaches head-on a large object at rest. The small object bounces straight back with a momentum of magnitude 6.19 kg m/s. What is the magnitude of the small object's momentum change in kg m/s? Q2 A force acts on a 4.708 kg mass as follows: the force starts at zero and rises to 60.334 N linearly in 2.24 seconds, it remains at 60.334 N for another 5.756 seconds,...

A ball of soft clay with mass 1 kg falls from a height of 10 m starting at rest. When the clay hits the ground it flattens and comes to a stop. Which of the following is true? Gravity does work on the ball equal to 980 J, and all this energy is dissipated during the deformation of the ball on impact. Gravity does work on the ball equal to 98 J, and all of this energy is dissipated during...

Each croquet ball in a set has a mass of 0.50 kg. The green ball, traveling at 14.6 m/s, strikes the blue ball, which is at rest. Assuming that the balls slide on a frictionless surface and all collisions are head-on, find the final speed of the blue ball in each of the following situations: a) The green ball stops moving after it strikes the blue ball. Answer in units of m/s. b) The green ball continues moving after the...
The ball B has a mass 5 kg and is attached to the end of a 1.7 m long rod whose mass may be negligible. If the shaft is subjected to a torque of M = 3t2 + 2 N.m, where t is in seconds, determine the speed of the ball when t = 3 s. Given, the ball has a sp
The ball B has a mass 5 kg and is attached to the end of a 1.7 m long rod whose mass may be negligible. If the shaft is subjected to a torque of M = 3t2 + 2 N.m, where t is in seconds, determine the speed of the ball when t = 3 s. Given, the ball has a speed of 4.8 m/s when t = 0. Present your answers in m/s.
