Solve the problem.A projectile is fired vertically upward into the air, and its position (in meters) above the ground after t seconds is given by the function s(t) = -4.9t2 + 30t.a. Find the instantaneous velocity function v (t).b. Determine the instantaneous velocity of the projectile at t = 1 and t = 2 seconds.
A. a. v(t) = -9.8t + 30; b. v(1) = 20.2 m/s, v(2) = 10.4 m/s B. a. v(t) = 20.2t; b. v(1) = -20.2 m/s, v(2) = -40.4 m/s C. a. v(t) = 20.2t; b. v(1) = 20.2 m/s, v(2) = 40.4 m/s D. a. v(t) = -9.8t + 30; b. v(1) = -20.2 m/s, v(2) = -10.4 m/s
