A 5.60kg mass is pushed against a spring (k=2000N/m) such that the spring is compressed 12 cm. The mass is released, slides1.50 m down the incline, along which μ=0.140. Decide the kinetic energy as it reaches level ground.
Assume that the masses of the chains, pulleys, and ropes are negligible and the crate is rising with an acceleration of 2.9 m/s2. Determine the force also examine the tension in the upper chain.
