Please neatly show me how to solve these with all the correct steps and explain so I can understand the process. Thanks

Part (a) Suppose the force exerted by a spring is F(x) = -kx and the spring has constant k = 325 N/m. Then suppose a wooden cube with mass m = 6 kg traveling with an initial velocity on a level surface with kinetic coefficient of friction 0.250 presses against the spring and it compresses from x = 0 to x = 0.70 meters as it stops. What is the net work done? HINT: You need to integrate to solve.

Part (b) Refer to the picture below. If block A has mass M and block b has mass m, find the acceleration of block B assuming that the acceleration of block A equals two times the acceleration of block B. You must show all the steps.

    Please show all work 1. A horizontal massless spring with spring constant 300 N/m is compressed 20 cm. The spring launches the block of mass 1 kg. When the block reaches the other side of the room it compresses a massless spring 600 N/m as shown in the figure. The surface is frictionless except the small part of length 2m, which has a coefficient of kinetic friction 0.2. Find the maximum compression of the spring 600 N/m. 300 N/m 600N/m...

    chap07-P33 Please write the answer neatly for a thumps up, thank you! The block in the figure lies on a horizontal frictionless surface, and the spring constant is 50 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 3.0 N pulls the block in the positive direction of the x axis, stretching the spring until the block stops. When that stopping...
