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.

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

the solution is in the attached Word file

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
