A body builder exerts a force of 150 N against a bullworker and compresses it by 20 cm. Caculate the spring constant of the spring in te bullworker.

Text Solution

Verified by Experts

The body builder exerts a force = 150 N,
Compression, x = 20 cm= 0.2 m
`:.` Total force exerted by the man, f
`=kx= 150 N`
`=> k= 150/0.2 = 1500/0.2 = 750 N/m`.
