a 20.5 kg ball moving at 38.5 m/s on a horizontal, frictionless surface runs into a light spring of force
constant 5.15 n/cm. use the work-energy theorem to find the maximum compression (in m) of the spring.

7.68 m

Explanation:

Kinetic energy in ball = elastic energy in spring

KE = EE

½ mv² = ½ kx²

mv² = kx²

x = v √(m / k)

x = (38.5 m/s) √(20.5 kg / 515 N/m)

x = 7.68 m

powerful computers now, not then

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
