Find v(t), the instantaneous velocity funciton.
Find the average velocity on the interval [1, 2]
HINT: Solution should be negative because the object is falling. Use s(t) to compute average velocity.
Find the intstantaneous velocity of the object at 2 seconds.
Find the velocity of the coin when it reaches the ground. Round to three decimal places.
HINT: Solve s(t) = 0. Then plug that result into v(t).
Find v(t), the instantaneous velocity funciton.
Find the velocity of the object at 5 seconds.
Find the velocity of the object when the object hits the ground.
