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 23 m/s at an angle of 69° 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?
its initial vertical speed was 23Sin69
its final vertical speed was zero.
solve for height
