Use the vertical motion model (h=-16t^2 + vt + s ) to solve the problem. A frog jumps from the ground with an initial vertical velocity of 20 feet per second. After how many seconds does it land on the ground?

In this case, v = 20, and the frog jumps from the ground, so s = 0. What the question is asking you is when does the height = 0? Once you set up your equation you can either solve by factoring or using the quadratic formula.

h= -16t^2 + 20t t=0,5/4 seconds
