Question

A cannon is placed at the edge of a cliff of height H overlooking the ocean. The cannon has a muzzle velocity V0 and is pointed at a positive angle THETA above the horizontal.

The kinetic energy of the projectile when it hits the water depends on ________________.
A: H only B: V0 only C: THETA only D: H and V0 only E: H and THETA only F: THETA and V0 only G: H, V0 and THETA


The kinetic energy of the projectile at the its highest point depends on ______________.
A: H only B: V0 only C: THETA only D: H and V0 only E: H and THETA only F: THETA and V0 only G: H, V0 and THETA

Explanation / Answer

1.KE depends on the final velocity , which depends on the

V0 and THETA (does not depend on H because, H is dependent upon Vo and theta )
so KE also depends on : V0 and THETA

so OPTION F

2. option F:THETA and V0 only
