Which would take more force to stop in 17. 3 seconds: a 3. 2 kg ball rolling in a straight line at a speed of 0. 3 m/sec or a 4. 1 kg ball rolling along the same path at a speed of 1. 2 m/sec?

The second one (4.1 kg ball)

This is because the mxv is greater than the other one.

For the 4.1kg ball, the force it’s moving on is 4.92N

As for the 3.2kg ball, it’s moving with a force of 0.9N. Much less than the other one.
