Hello I need some help with these 2 questions. If you could please show me all your work on a separate sheet of paper with the solutions/answers that would be great!

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(t) = -4.912 + 30t. Find the instantaneous rate of change (the velocity function) at any time using Jim fleth)-f(al Determine the instantaneous rate of change (ie. the velocity) at: a) t = 2 b) t = 5 Video Lesson Tou You I. students may want to won the inductor's Funcion before attempting this next question. 4.
