Question

Gliders with masses 0.140kg and 0.230kg are at rest on an air track with a spring between them. The spring is compressed 1.25 cm and then released. The lighter glider moves off at 0.760m/s .

Part A

Find the speed of the heavier glider.

Part B

Find the spring constant k, assuming all the spring's potential energy was converted into the gliders'kinetic energy.

Explanation / Answer

m1*v1 = m2*v2

v2 = 0.46 m/s

=------------

0.5*k*x^2 = 0.5*m1*v1^2 + 0.5*m2*v2^2

k = 829.0048 N/m
