Answer to Question #222005 in Physics for caleb villarreal

Question

 If the spring constant k of a pogo stick is 3100 N/m and the weight of the person on the pogo stick is 760 N, how much is the spring in the bottom of the pogo stick compressed?

Answer 1

The Hooke's law says

$$F=kx$$

Hence, the compression of the spring

$$x=\frac{F}{k}=\frac{760\:\rm N}{3100\:\rm N/m}=0.245\:\rm m$$
