Problem

ProblemA 4-kg block moving on a flat surface strikes a massless, horizontal spring of force constant 600 N/m with a 20 m/s. The block-surface coefficient of friction is 0.5. Calculate the maximum compression that the spring will experience.

A

Δx = 0.63 m

B

Δx = 1.60 m

C

Δx = 1.63 m

D

Δx = 1.67 m
