Question

The air-track carts in the figure are sliding to the right at 1.0 m/s. The spring between them has a spring constant of 140 N/m and is compressed 4.2 cm. The carts slide past a flame that burns through the string holding them together. The speed of the 100-g cart is 0.36 m/s.

What is the speed of the 300-g cart?

The air-track carts in the figure are sliding to the right at 1.0 m/s. The spring between them has a spring constant of 140 N/m and is compressed 4.2 cm. The carts slide past a flame that burns through the string holding them together. The speed of the 100-g cart is 0.36 m/s. What is the speed of the 300-g cart?

Explanation / Answer

m1 = 0.100 kg
m2 = 0.300 kg
k = 140 N/m
d = 0.043 meter

In this problem, both energy and momentum are conserved:

ES = KE1 + KE2
