3CQ A 0.2 kg plastic cart and a 20 kg lead cart can 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, is the momentum of the plastic cart greater than, less than, or equal to the momentum of the lead cart? Explain.
Step 1of 3 impulse is the measure of how much the force changes the momentum of an object. Impulse= force ×time= F × t p And we know that F = t So Impulse is J = p J =p f p i
