Answer to Question #265188 in Physics for Marie

Question

You are standing on a very slippery icy surface and throw a 1 kg football horizontally at a speed of 7.3 m/s. What is your velocity (in m/s) when you release the football? (Assume your mass is 66 kg and that the positive direction is the direction of motion of the football. Indicate the direction with the sign of your answer.)

Answer 1

$0=m\vec v+M\vec V\to$

$mv=MV\to V=mv/M=1\cdot7.3/66=0.11\ (m/s)$

If we take into account the direction then $V=-0.11\ (m/s)$ . Answer
