Question

The spring shown in the figure (with spring constant k = 60000) is compressed 65 cm and is used to launch a 56 kg. physics student along a frictionless track. The height of the student at the start is H = 12 m.

(A)What is the student's speed (in m/s) just after losing contact with the spring?

(B)What was the student's speed (in m/s) at the bottom of the hill?

(C)How far up the incline (in meters) does the student slide?

Now consider the track as frictionless until it starts up the ?=28^o incline, and then friction kicks in.

(D)If the student only makes it 59.8 m up the incline, how much work (in J) was done by friction?

(E)What was the coefficient of friction on the ramp?
