A 2-kg block is pushed against a spring with k =
500 N/m, compressing the spring by 20 cm.
The block is then released, and the spring
projects it along a frictionless horizontal surface
and then up a frictionless incline of angle 45° as
shown in the figure. What is the maximum
height it travels up the incline before
momentarily coming to rest?
