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

USE GRESA METHOD FOR THE SOLUTION 1. A 5.0 million-pound rocket takes off from rest in Houston, Texas. The rocket has attained 150 kph (kilometers per hour) of speed 8.00 s after the launch. Then, at the end of the first minute, its speed is 1,500 kph. (a) What is the average acceleration of the rocket, in m/s2, during the first 8.00 s? (b) What is the average acceleration of the rocket, in m/s2, between the first 8.00 s and the end of the first minute? (c) Suppose the acceleration is constant, but not necessarily the same, in both intervals stated in (a) and (b), how much distance has the rocket covered during the first 8.00 s, and (d) during the interval from 8.00 s to the end of the first minute?
A bicyclist starts from rest and accelerates at a rate of 4.00 m/s2 for 3.00 s. The cyclist then travels for 24.0 s at a constant speed. How far does the cyclist travel? Use the Problem-solving method to explain your thoughts clearly. Use graphics if necessary.
Pablo and Jacob are running a half marathon. Jacob is d = 55 m behind Pablo and both are running at the same speed of s = 3.7 m/s. At a particular moment, Jacob begins to accelerate forward at a constant rate of a = 0.069 m/s2. Write an expression for the distance Jacob traveled as he was accelerating to catch Pablo in terms of variables from the problem statement
