Energy & Momentum Calculations Assessment
A 1.0 kg puck sliding at 15 m/s along some horizontal frictionless ice strikes and compresses a horizontal spring attached to one end of the ice rink. If the spring has a constant of 35 N/m, what is the maximum compression of the spring?

1. Ek=(1/2)mv²
Ep=(1/2)(KΔx)²

If spring has no mass,
equate Ek and Ep to solve for Δx.
