A 2.00kg block is pushed against a spring with force constant k=400N(m^-1), compressing it 0.180m. The block is then released and moves along a frictionless horizontal surface and then up frictionless incline with slope angle 37.0degrees.
a. What is the speed of the block as it slides along the horizontal surface after having left the spring?
b. How far does the block travel up the incline before starting to slide back down.
A) Speed(v)=2.55m/s B) S=0.54m
