Here's my predicament... A 30.0 kg shopping cart full of groceries sitting at the top of a 2.0 meter hill rolls until it hits a tree stump at the bottom of the hill. Upon impact, a .25 kg can of peaches flies out of the cart. What is the velocity of the can as it leaves the cart? I tried solving the problem, but the answer that I got really doesn't make any sense. First I solved for the final velocity of the cart before it hit the tree stump, and I got 6.26 m/s. Then, when I solved for the velocity of the can, I got an answer of 750 m/s, which is very unrealistic. Can someone point me in the right direction, or point out where I went wrong?
