Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

The lower block of mass m2 = 3.2 kg is pulled on by a rope with a tension force of 28 N. The upper block has mass m1 = 1.8 kg. The coefficient of kinetic friction between the lower block and the surface is 0.32. The coefficient of kinetic friction between the lower block and the upper block is also 0.32. What is the acceleration of the 3.2 kg block?
Solve (1) please
Choose the correct answer choice.
Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 80 N/m, attached to a 22-kg block in an incline (0 = 55°). With the spring initially at equilibrium position, the block was pushed 0.5 meters up the incline by a 42-N external force applied parallel to the path. If the coefficient of kinetic friction is 0.3, determine the work done by the spring (in Joules). Use g = 9.81 m/s². CO
