Can someone help me this one

Question 1 5 pts The distance ( in feet) a ball rolls down an incline is modeled by the function f (t) = 14t2 , t is seconds after ball begins rolling. We want to conclude about the velocity (speed) at time =5 seconds by finding average velocity in small time intervals near 5 seconds. Don't Round answers. Open Desmos, enter f (t) = 14t2. enter expression for average rate of change in distance, in a small time interval h: (f(5th ) -f(5 ) ) - and change h for each question. A. The average velocity of the ball in the small time interval [5, 5.1] seconds, where h=0.1 is feet / sec B. The average velocity of the ball in the smaller time interval [5, 5.01] seconds, where h=0.01 is feet / sec C. The average velocity of the ball in the smaller time interval [5, 5.001] seconds, where h=0.001 is feet / sec D. The average velocity of the ball in the smaller time interval [5, 5.0001] seconds, where h=0.0001 feet / sec E. The instantaneous velocity of the ball at time t=5 seconds is feet / sec (answer this using concept of limits)
