A spring with a spring constatn of 1200 N/m is placed at the bottom of an inclined plane with an angle of 30 degrees with the horizontal. A 0.5 kg block is also placed on the inclined plane and pressed against the spring. The spring is compressed 0.05 m. The block is then released and moves up the inclined plane to reach its maximum height.
a. Find the change in gravitational potential energy when the block reaches the maximum height. THe initial point is the release point.
b. find the speed of the block when it leaves the spring.
c. how far up the incline plane will the block move before it stops.
d. If there is friction with coefficient of kinetic friction being .3 how far up the inclined plane will the the block move in this case.
