A0.2 kg plastic cart and a 20 kg lead cart can both roll without friction on a horizontal surface. equal forces are used to push both carts forward for a time of 1 s, starting from rest. after the force is removed at t = 1 s, the momentum of the plastic car is the momentum of the lead car.

The momentum of the plastic car is same the the momentum of the lead car.

Explanation:

Given that,

Mass of plastic car = 0.2 kg

Mass of lead = 20 kg

Time = 1 sec

Equal forces are used to push both carts

We need to calculate the momentum

Using formula of momentum

Put the value into the formula

For plastic cart,

...(I)

For lead cart,

...(II)

Divided equation (I) by equation (II)

Hence, The momentum of the plastic car is same the the momentum of the lead car.
