Question

A ball's height (in units of meters) after tt seconds is modeled by: h(t)=−t2+5t+6h(t) = $$-t^2 + 5t + 6. $$Find the time(s) when the ball is located at ground level where h=0h = 0.

Accepted Answer

t=6t = 6 seconds

Answer

There are no real times because the quadratic opens downward and never meets the ground

Answer

t=−1t = -1 and t=6t = 6 seconds

Answer

t=−6t = -6 and t=1t = 1 second

A ball's height (in units of meters) after tt seconds is modeled by: h(t)=−t2+5t+6h(t) = -t^2 + 5t + 6. Find the time(s) when the ball is located at ground level where h=0h = 0.

A ball's height (in units of meters) after $t$ seconds is modeled by: $h (t) = - t^{2} + 5 t + 6$ . Find the time(s) when the ball is located at ground level where $h equals 0$ .
