Homework Answers
1) Zero kgm/s. Both are in rest initially. Hence total momentum is zero.
2)The momentum ball is not conserved in any direction, since a force is applied by the cannon on ball.
3) The X component of system is conserved for cannon ball system. There is no external force in X direction, in Y direction there is gravitational force hence Y component is not conserved.
4) Canon ball earth system momentum is conserved in both X and Y directions. There is no external force in any direction.

A circus act consists of a performer (a "human cannonball") being launched from a cannon into a net at the other end of the stage. The performer (mass 60 kg) leaves the cannon at a speed of 25 m/s at an angle of 30o above horizontal. She comes out of the cannon at a height of 2 meters above the ground and lands in the net at a horizontal distance of 45 meters away from the launch point. 1. How...
