A projectile is launched from point O at an angle of 22° with an initial velocity of
15 m/s up an incline plane that makes an
angle of 10° with the horizontal. The
projectile hits the incline plane at a point
M. Find the distance from point o to
point M.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

multiply 2kg by latent heat of vap

what is the actual question though?
