A rock climber throws a small first aid kit to another climber who is higher up the mountain. The initial velocity of the kit is 21 m/s at an angle of 58° above the horizontal. At the instant when the kit is caught, it is traveling horizontally, so its vertical speed is zero. What is the vertical height between the two climbers?
Easy. YOu know it went h height, with an initial vertical velocity of 21sin58.
Vf^2=Vi^2 + 2gh solve for h.
