Identify the function that models ignoring air resistance a ball being thrown in the air with an initial velocity of 70 ft/s from a height of 5 feet

The required function is .

Explanation:

It is given that the ball being thrown in the air with an initial velocity of 70 ft/s and from a height of 5 feet. It means

Initial velocity = 70 ft/s

Initial height = 5 feet

The general function that approximate the height  in feet of a projectile on the earth after time t is

            .... (1)

Where, v₀ is initial velocity and h₀ is initial height.

Substitute and in equation (1).

Therefore, the required function is .
