A25 kg child bounces on a pogo stick. the pogo stick has a spring with spring constant 2.0x10^4 n/m. when the child makes a nice big bounce, he finds that at the bottom of the bounce he is accelerating upwards at 9.8 m/s^2. how much is the spring compressed?

the spring is compressed by x = 2.45 cm

Explanation:

As we know that at the bottom of the bounce the net force on the child is given as

here we know that

now we will have

so the spring is compressed by x = 2.45 cm

need to see circuit to get time constant

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
