Substitute the values into the vertical motion formula: h = –16t2 + vt + c. Let h = 0.

Answer 1

When h = 0, the object has hit the ground, so we can find the time it takes for this to occur by solving for t:

0 = -16t^2 + vt + c

We do not have enough information to solve for t since we do not know the values of v and c.

Answer 2

t = (v±√(v^2-64c))/32

Answer 3

Actually, the correct formula for solving for time when h=0 is:

t = (v ± √(v^2 + 64c)) / 32

This is obtained by setting h=0 in the equation h = -16t^2 + vt + c and solving for t using the quadratic formula.
