1.
a 20 kg cannon is fired from a cannon with a muzzle speed of 1000 m/s at an angle of 37º with the horizontal .
a second ball is fired at an angle of 90º. use the conservation of energy prinnciple to find .
- the maximum height reached by each ball.
- the total mechanical energy at the maximum for each ball let y=0 at the cannon
2.
a force acting in a particle moving in a xy plane is given by F=(2yi + xˆ2j ) N, where x and y are in meters. the particles moves from the origin to a final position having coordinates x= 5m
and y =5m . calculate the work done by F along:
- OAC
- OBC
- OC
- Is F conservative or nonconservative. Explain
