Question

A frictionless cart attached to a spring vibrates with amplitude A. Part A Determine what fraction of the total energy (Etot) of the cart-spring system is elastic potential energy (Us) and what fraction is kinetic energy (K) when the cart is at position x=A/2. Express your answers using two significant figures separated by a comma.

Answer 1

Answer:

the fraction of the total energy (Etot) of the cart-spring system is elastic potential energy (Us) is 0.25

the fraction is kinetic energy (K) when the cart is at position x=A/2 is 0.75
