I'm pretty sure this is an easy problem but I don't know what formula to use - At the local grocery store, you push a 16.2 kg shopping cart. You stop for a moment to add a bag of dog food to your cart. With a force of 12.0 N, you now accelerate the cart from rest through a distance of 2.02 m...

Thank you-- Problem: A 50 kg boy runs at a speed of 10 m/s and jumps onto a cart. The cart is initially at rest. If the speed of the cart with the boy on it is 2.50 m/s, what is the mass of the cart? I don't know what to do. This probelem seems very simple but I don't know where to start...

A person is sitting in a heavy cart with wheels. The person pulls a rope attached to a rigid support, but the cart does not move. Where does the energy expended by the person go? Is it converted into heat or stored somewhere as potential energy, please clarify?

Me and my buddy had a discussion the other day. Imagine the scenario with the donkey that has a danglin carrot in front of him. If we swap the donkey for a cart and the carrot for a magnet, what would happen? My buddy was pretty sure that the cart would move, and I thought that it wouldn't...

I'm having trouble getting started on this entire problem. I've re-drawn it, I'm given the mass of the cart, and the radius of the loop.. but I have absolutely no idea how I can calculate even the first part of this (minimum high h). I'd greatly appreciate any help anyone could offer. Thank...
