A 2.00-kg block is pushed against a spring with negligible
Chapter 9, Problem 42P(choose chapter or problem)
A 2.00-kg block is pushed against a spring with negligible mass and force constant k = 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 37.0o (Fig. P7.40). (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?

QUESTION:
A 2.00-kg block is pushed against a spring with negligible mass and force constant k = 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 37.0o (Fig. P7.40). (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 0 Slope of the inclined plane =37 (a)
