An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.

How to find when will the object hit the ground?

According to the problem,

  • An object is dropped from a height of 144 feet

The given function is h(t) = -16t2 + 144.

When the object reaches the ground h(t) becomes 0

So, the equation will be 0 =  -16t2 + 144.

Solving the equation we get t = 3 seconds
