Aball is tossed into the air at 20 feet per second from a height of 7 feet. how long will it take the ball to reach the ground? use the formula sequals negative 16 t squared plus v subscript o baseline t plus s subscript o, where v subscript o baseline equals initial velocity, s subscript o equalsinitial altitude, and s equals altitude in feet after t seconds.

We have been given that the ball is tossed into air at a speed of 20 feet per second and from a height of 7 feet.

We are supposed to use the formula:

Upon substituting the given values of initial velocity and initial altitude, we get:

We need to figure out the time that will take the ball to reach the ground. In order to do so, we will substitute s(t)=0 and solve for t.

Upon using quadratic formula, we get:

Upon finding the values of t using calculator, we get t=-0.285, 1.535

Therefore it will take the ball approximately 1.54 seconds to hit the ground.
