Question

A horizontal spring with spring constant 950 N/m is attached to a wall. An athlete presses against the free end of the spring, compressing it 7.0 cm. How hard is the athlete pushing?

Answer 1

Answer:

66.5N

Explanation:

F = kx

Where F = force

K = spring constant

x = compression

Given

K = 950N/m

x = 7.0cm

F = ?

First convert the compression to meters .

7.0cm = 7.0 x 0.01

= 0.07 meters

Therefore

F = 950 x 0.07

= 66.5N
