One last physics question?

A block weighing 2 kg is pushed a spring with negligible mass and a spring constant of k=350 N/m, compressing it 0.25 m. If the block is released, it moves along a horizontal surface (frictionless) and then up an incline (frictionless) with a slope of 25 def. a) What is the speed of the block as it slides across... show more A block weighing 2 kg is pushed a spring with negligible mass and a spring constant of k=350 N/m, compressing it 0.25 m. If the block is released, it moves along a horizontal surface (frictionless) and then up an incline (frictionless) with a slope of 25 def.

a) What is the speed of the block as it slides across the flat surface after the spring?

b) How far can the block travel up the ramp before heading back down?

Thanks all, much appreciated.
