$Arrow$ Calculus Problem - Velocity

An object is dropped form a 75-ft cliff. Its height in feet above the beach after t sec is given by h(t)=75-16t^2.

A) Find the average velocity during the interval from t=1 to t=2

B) Find the instantaneous velocity at t=2

A) Find the average velocity during the interval from t=1 to t=2

$\bar{v} = \frac{h(2) - h(1)}{2 - 1}$

B) Find the instantaneous velocity at t=2

$v(2) = \lim_{t \to 2} \frac{h(t) - h(2)}{t - 2}$

ok?
