The height of an acorn falling out of a tree is given by h=-16t+b. If an acorn takes 1 second to fall to the ground what is the value of b?

From the equation given above,

h = - 16t + b

If it takes 1 second to fall to the ground, we substitute 1 to t of the equation,

h = - 16 (1) + b

Adding 16 to both sides of the equation, the value of b would be

h + 16 = b

or

b = h + 16
