    1. The problem statement, all variables and given/known data

    A golfer wishes to chip a shot into a hole 60 m away on flat level ground. If the ball sails off at 50°, what speed must it have initially? Ignore aerodynamic effects.

    2. Relevant equations

    xf = xi + vxi(t)
    vx = vi(cos)angle


    3. The attempt at a solution

    How would I plug this in>
