Question 876697
a ball is tossed into the air at 40 feet per second from a height of 5 feet. how long will it take the ball to reach the ground?
-------------
A commonly used equation is
{{{h(t) = -16t^2 + vt + h}}}, t in seconds, h in feet
------
{{{h(t) = -16t^2 + 40t + 5}}}
Find when
{{{h(t) = -16t^2 + 40t + 5 = 0}}}
{{{-16t^2 + 40t + 5 = 0}}}
It's a quadratic, solve for t.
Ignore the negative value.
