A small pickup truck that has a camper 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?

Step-by-step solution In this problem we have to find what will be the effect of the dogs on the motion of the center of mass of the system when a pickup truck with two dogs in the back of the truck slowly coasts toward a red light with negligible friction which causes various inelastic collisions of the two dogs with each other and the walls.so,What is their effect on the motion of the truck. Step 1 of 3 The formula to find the position of center of mass is, Here is the Centre of mass, is mass of the first dog, is mass of the second dog, is mass of the truck. Here , and are the distances of first dog, second dog and the truck from a reference point respectably . Step 2 of 3 The mass of the truck is much more than the combine mass of the two dogs. Therefore, the motion of dogs does not affect the motion of the center of mass of the system.
