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?

  • physics -

    its initial vertical speed was 23Sin69

    its final vertical speed was zero.

    Vf^2=Vi^2-2*9.8height
    solve for height
