Question

A 500 g glider sits on a frictionless horizontal air track, connected to a spring of negligible mass with force constant k. You push the glider to a maximum displacement of x= 25cm and release from rest. if the speed of the glider is 73 cm/s when x= -10 cm from equilibrium, what is the value of the spring constant k?

Explanation / Answer

0.5*kx2 = 0.5*mv2

k = .5*.73*.73/(.25*.25) = 4.2632 N/m
