A clown was shot out of a cannon at ground level. Her height above the ground at any time (t) was given by the function h(t) = -15t2 + 15t
What was height at t(1), t(2),and t(3)?
The flight will last how many seconds??

  • Math -

    figure h when t=1, 2, and 3

    the flight finished when h(t)=0
    solve for t.
