Let’s suppose you throw a ball straight up with an initial speed of 50 feet per second from a height of 6 feet.

a.Find the parametric equations that describe the motion of the ball as a function of time.
b.How long is the ball in the air?
c.Determine when the ball is at maximum height. Find its maximum height.

i haven't got the slightest idea of how to do this.

  • math - ,

    a = -32 ft/s^2
    v = 50 -32 t
    h = 6 + 50 t - 16 t^2

    find t when h = 0 (the positive answer)

    max height is when v = 0, find t and h then.
