You hit a tennis ball from just above the ground. It leaves the racket at 15m/s going 10 degrees upward.

Does the ball land before reaching the baseline at the other end of the court, 25m away?
Yes, It does land within the court.

If you struck the ball harder but at the same angle, what's the maximum initial speed it could have and still land in the court?

  • Physics - ,

    Range = (Vo^2/g)*sin2A = 7.85 m
    well within the opposite court.

    If (Vo^2/g)*sin2A = 25 m,
    Vo^2 = 716 m^2/s^2
    Vo = 26.8 m/s
