Question

A car suspension spring has a spring constant of 2000 N/m. Calculate the

elastic potential energy stored in the spring when it is compressed by 8 cm.

Answer 1

Wp = 6.4 J

Step-by-step explanation:

Given:

k = 2 000 N/m

Δx = 8 cm = 0.08 m

________________

Wp - ?

Compressed spring energy:

Wp = k·(Δx)² / 2

Wp = 2 000·(0.08)² / 2 = 6.4 J
