Question

A 0.5-kg block slides along a horizontal frictionless surface at 2m/s. It is brought to rest by compressing a very long spring of spring constant 800N/m. The maximum spring compression is:

Answer 1

Fb = M*g = 0.5 * 9.8 = 4.9 N. = Force of block.

d = 4.9N/800N * 1m = 0.006125 m. = 0.6125 cm.
