Question

only need answer for 2b Bruno pushes a sled starting from rest with a constant force in the positive x direction for 10s. 1) Explain what will happen to each of the following a) The momentum of the sled b) The kinetic energy of the sled c) The potential energy of the sled 2) If Bruno stops pushing the sled and it comes to a stop after a distance of 10m, a) How does the work done on the sled by Bruno compare to the work done on the sled by non- conservative forces? b) How does the impulse provided to the sled by Bruno compare to the change in momentum of the sled?

Explanation / Answer

2b) Both are same.

By impulse-momentum theorem, impulse provided is equal to the change in momentum.
