In Algebra, you drop a penny from a height of 16 feet. After how many seconds does the penny land on the ground? Formula: h = -16t^2 + vt + s

Assuming no friction or terminal velocity:

h = 0 when it hits the ground find t

0 = 16t^2+vt + s v = 0 as you drop it and s= 16 at the starting point

0= -16t^2 + 16

-16 = - 16t^2

1= t^2 t=1 sec
