The spring has a force constant of 5000 N/m, the block has a mass of 6.20 kg, and the height of the hill is 5.25 m. A. Determine the compression of the spring such that the block just makes it to the top of the hill. Assume that there is no friction along the whole path. B. What coefficient of friction is needed along the horizontal plane (of length 2.75m) if the block is to reach only midway up the hill? C. In the same case as (B) where friction is present, at what height along the hill will the speed be 6m/s?

Question
The spring has a force constant of 5000 N/m, the block has a mass of 6.20 kg, and the height of the hill is 5.25 m.
A. Determine the compression of the spring such that the block just makes it to the top of the hill. Assume that there is no friction along the whole path.
B. What coefficient of friction is needed along the horizontal plane (of length 2.75m) if the block is to reach only midway up the hill?
C. In the same case as (B) where friction is present, at what height along the hill will the speed be 6m/s?
