Consider a long metal rod lying on the floor. One end of the rod is fixed to the wall. You add heat Q to the rod with a blow torch. During this process, due to thermal expansion, the rod increases in length from 1 m to 1.05 m. As it expands, the rod does some work, pushing a mass along the floor exerting a constant force of 1000 N on the block. The total thermal energy of the rod increases...

A 4.5 kg box slides down a 4.8-m -high frictionless hill, starting from rest, across a 2.0-m -wide horizontal surface, then hits a horizontal spring with spring constant 520 N/m . The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.0-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.24. Part A What is the speed of the box just before...

ch05prob5.58 A system consists of a 4.6-kg cart and a 1.4-kg cart attached to each other by a compressed spring. Initially, the system is at rest on a low-friction track. When the spring is released, an explosive separation occurs at the expense of the internal energy of the compressed spring. The change in the spring's internal energy during the separation is 1.0 kJ . Part A What is the speed of 1.4-kg cart right after the separation? Express your answer...
