A Small pickup truck that has a caliper shell slowly coasts toward a red light with negligible friction. Two dogs in the back of the truck are moving and making various inelastic collisions with each other and the walls. What is the effect of the dogs on the motion of the center of mass of the system (truck plus entire load)? What is their effect on the motion of the truck?
A tennis ball of mass 57.0 g is held just above a basketball of mass 590 g. With their centers vertically aligned, both balls are released from rest at the same time, falling through a distance of 1.20 m, as shown in Figure P6.45. (a) Find the magnitude of the basketballs velocity the instant before the basketball reaches the ground. (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball so that it collides with the tennis ball just above it. To what height does the tennis ball rebound? Figure P6.45
Two identical ice hockey pucks, labeled A and B, are sliding towards each other at speed v. Which one of the following statements is true concerning their momenta and kinetic energies? (a) pA=pBandKEA=KEB (b) pA=pBandKEA=KEB (c) pA=pBandKEA=KEB (d) pA=pBandKEA=KEB
Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at 5.00 m/s as in Figure P6.40a. After the collision, the orange disk moves in a direction that make an angle of 37.0 with the horizontal axis while the green disk makes an angle of 53.0 with this axis as in Figure P6.40b. Determine the speed of each disk after the collision. Figure P6.40
(a) If two automobiles collide, they usually do not stick together. Does this mean the collision is elastic? (b) Explain why a head-on collision is likely to be more dangerous than other types of collisions.
Two particles with masses m and 3m are moving toward each other along the x axis with the same initial speeds i. The particle with mass m is traveling to the left, and particle with mass 3m is traveling to the right. They undergo a head-on elastic collision, and each rebounds along the same line as it approached. Find the filial speeds of the particles.
A man of mass m 1 = 70.0 kg is skating at v1 = 8.00 m/sbehind his wife of mass m 2 = 50.0 kg, who is skating at v2 = 4.00 m/s. Instead of passing her, he inadvertently collideswith her. He grabs her around the waist, and they maintaintheir balance. (a) Sketch the problem with before - and - afterdiagrams, representing the skaters as blocks. (b) Is the collisionbest described as elastic, inelastic, or perfectly inelastic? Why?(c) Write the general equation for conservation of momentumin terms of m 1, v 1, m 2, v 2, and final velocity vf . (d) Solve themomentum equation for vf . (e) Substitute values, obtaining thenumerical value for vf , their speed after the collision.

Comic-strip hero Superman meets an asteroid in outer space and hurls it at 800 m/s, as fast as a bullet. The asteroid is a thousand times more massive than Superman. In the strip, Superman is seen at rest after the throw. Taking physics into account, what would be his recoil velocity?
in his novel From the Earth to the Moon (1866), Jules Verne describes a spaceship that is blasted out of a cannon, called the Columbiad, with a speed of 12,000 yards/s. The Columbiad is 900 ft long, but part of it is packed with powder, so the spaceship accelerates over a distance of only 700 ft. Estimate the acceleration experienced by the occupants of the spaceship during launch. Give your answer in m/s2 (Verne realized that the "travelers would . . . encounter a violent recoil," but he probably didn't know that people generally lose consciousness if they experience accelerations greater than about 7g∼70m/s2.
1.A fireworks rocket is launched vertically into the night sky with an initial speed of 44.2 m/s. The rocket coasts afterbeing launched, then explodes and breaks into two pieces of equal mass 2.50 s later. (a) If each piece follows a trajectory that is initially at 45.0° to the vertical, what was their speed immediately after the explosion? (b) What is the velocity of the rocket’s center of mass before and after the explosion? (c) What is the acceleration of the rocket’s center of mass before and after the explosion?Explain and labled the drawing.
Spectators watch a bicycle stunt rider travel off the end of a60.0° ramp, rise to the top of his trajectory and, at that instant,suddenly push his bike away from him so that he falls verticallystraight down, reaching the ground 0.550 s later. Howfar from the rider does the bicycle land if the rider has massM = 72.0 kg and the bike has mass m = 12.0 kg? Neglect airresistance and assume the ground is level.
