Question
A toy car of mass m is pushed along a frictionless track so that it is moving at a speed v1. It hits a spring with
stiffness k at the end of the track causing the spring to compress. What is the maximum compression x of the
spring?
By conservation of energy.
K1 + U1 = K2 + U2
Some of the terms in the equation above are zero; thus it can be simplified to:
2 = 2
Isolating the compression x,
x = (
21
1/2
Suppose the mass of the toy car moving at 2.5 m/s is 0.0505 kg and the spring constant is k = 605 N/m, the
spring will experience a maximum compression of 0.0
84 m.
