Physics

A 40.0N force at an angle of 40.0° pulls a 5.00 kg block, itselfattached to a spring (k = 30.0N/m). The
block and the surface have a kinetic friction coefficient of 0.200.Initially, the system is at rest and the
spring is at its natural length. When the block has moved 40.0 cmto the right, and using the work-energy
principle, find:

a) the thermal energy dissipated.

b) the work done by the external force.

c) the work done by the spring.

d) the final velocity of the block.
