Answer: A 2.00-kg block is pushed against a spring with
Chapter 7, Problem 42P(choose chapter or problem)
A 2.00-kg block is pushed against a spring with negligible mass and force constant 400 N/m, compressing it 0.220 m. When the block is released, it moves along a frictionless, horizontal surface and then up a frictionless incline with slope \(37.0^{\circ}\) (Fig. P7.42). (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?

ANSWER:
Solution to 42P
Step 1
Mass of the block =2kg
Distance the spiring is compressed =0.220m
Spring constant =400N/m
Slope of the inclined plane =370
