Physics

A stone is thrown upward with an initial velocity of 25 m/s at an angle of 30° to the ground.
A) show that the vertical component of the velocity at the start is 12.5 m/s upwards.
B)with out doing any calculations, state what the stone's vertical velocity will be when it again reaches ground level.

  1. (A) 25 sin30° = 25 * 1/2
    (B) same as when it went up, but downward.
