3. A science project studying catapults sent a projectile into the air with an initial velocity of 30 m/s. The formula for distance (s) in meters with respect to time in seconds is S = -4.9t2 + 30t. Find the instantaneous rate of change (and thus the velocity at any time) using lim J(ath)-f(2) and then find the instantaneous rate of change at: a. t = 1 b. t = 3
