When an 80.0-kg man stands on a pogo stick, the spring is compressed 0.120 m. (a) What is the force constant of the spring? (b) Will the spring be compressed more when he hops down the road?

a.6533.333 N/m

b.Yes,the spring will be compressed more when the person hops down the road .

Explanation:

Mass of man=80 kg

Spring compressed by x=0.12 m

a.We have to find the force constant of the spring.

Spring constant=

Using the formula

Spring constant,N/m

Spring constant=

b.The spring will be compressed more when the person hops down the road because when the person hops down then the kinetic energy of person will be converted into potential energy during the road hit.
