Question

A ball is thrown upwards in the air. The height h(t) in feet, of the ball above ground t seconds after being thrown is determined by the expression h(t)=-16t^2+20t+2.

What is the meaning of 2 in the expression?

Answer 1

1. The ball is thrown from a height of 2 ft

Explanation:

Since 2 does not have a variable that would be the y-intercept; the y-intercept it where the ball is first getting thrown from.
