Create and complete a table with your answers for the runner. A runner has an  initial velocity of 3.5 m/s from time t=0 to t=5sec (assume acceleration is 0 for first 5 sec). From t=5 to  t=10, the runner slows down slightly to 2.8 m/s at t=10 (assume constant acceleration). Then they  accelerate to 5.2 m/s at a constant rate from t=10 to t=20. From t=20 to t=25 their velocity is constant  at 5.2m/s. Calculate the accelerations over the intervals 0-5sec, 5-10sec, 10-20sec, and 20-25sec. Calculate the initial and final velocities over the intervals 0-5sec, 5-10sec, 10-20sec, and 20-25sec. Calculate the position & displacement changes in the intervals 0-5sec, 5-10sec, 10-20sec, and 20- 25sec. Calculate the location of the runner at t = 5s, t=10s, t=20s, t=25s
