A(n) 1.9-kg copper block is given an initial speed of 2.9 m/s on a rough horizontal surface. Because of friction, the block finally comes to rest.
(a) If the block absorbs 85% of its initial kinetic energy as
internal energy, calculate its increase in temperature. °C
(b) What happens to the remaining energy?
- a. It becomes chemical energy.
- b. It is so minute that it doesn't factor into the equation.
- c. It is absorbed by the horizontal surface on which the block slides.
- d. It vanishes from the universe.

A block of mass 0.528 kg slides with uniform velocity of 3.60 m/s on a horizontal frictionless surface. At some point, it strikes a horizontal spring in equilibrium. If the spring constant is k = 26.1 N/m, by how much will the spring be compressed by the time the block comes to rest? b. What is the amount of compression if the surface is rough under the spring, with coefficient of kinetic friction µk = 0.411?
