player kicks football from ground level with velocity of32 m/s at an angle of 40 degrees above horizontal. What is hang time of football?

How far does the ball travel horizontally before hitting the ground?

What is the maximum height that the ball reaches?

  • physics - ,

    Resolve the kickoff velocity into the horizontyal components Vx = 32 cos 40 and vertica component Vy = 32 sin 40.

    There are formulas that relate the hang time (T) and the maximum height (H) to Vy. Get to know them.

    Vy = sqrt(2 g H)
    T*g = Vy

    The "hang time" T times Vx is the distance the ball travels horizontaly before hitting gthe ground.
