A 2 \(\text{kg}\) block is released from rest at the top of a smooth incline of height h. It then slides down onto a rough horizontal surface of length 4 \(\text{m}\) where the coefficient of kinetic friction is 0.20. The block finally compresses a spring of spring constant k = 800 \(\text{N/m}\) until it momentarily comes to rest, compressing the spring by 0.10 \(\text{m}\). Take g = 10 \(\text{m/s^2}\). Find the minimum height h required.

A. h = 1.5 \(\text{m}\)

Correct Answer B. h = 1 \(\text{m}\)

C. h = 1.2 \(\text{m}\)

D. h = 0.8 \(\text{m}\)

Correct Answer

Correct Option:

h = 1 \(\text{m}\)
