<p>If you could answer these questions showing work that would be great. </p>
<p>27.) A 91 kg man lying on the surface of negligible friction shoves a 68 g stone away from him, giving it a speed of 4.0m/s. What is the initial velocity of the other block?</p>
<p>29.) A 75 kg man is riding on a 39 kg cart traveling at a speed of 2.3m/s. He jumps off with zero horizontal speed relative to the ground. What is the resulting change in the speed of the cart?</p>
<p>Thanks.</p>
