Physics

a crate of stuffed kittens with a mass of 1kg compresses aspring a distance of 2.84m. The spring has a spring constant of250N/m. The crate is released and slides across a rough surfacewith a kinetic friction coefficient of 0.38 for a distance of 62mbefore colliding with and sticking to another crate. The secondcrate is filled with cans of smoked turkey and has a mass of 2kg.The two crates then slide horizontally off a vertical cliff with aheight of 15m and land on the level ground below. Use g -9.8m/s^2,and answer the following:(no picture needed)
a) what maximum acceleration does the crate of stuffed kittensachieve due to the spring?
b) How fast is the crate of stuffed kittens moving when itcollides with the crate of smoked turkey?
c) how fast are the two crates moving when they launchhorizontally off the cliff and how fast are the two crates movingjust before they hit the ground?
d) How much farther would the spring need to be compressed inorder to double the final speed of the two crates at the momentthey are about to hit the ground?
