SUMMARY
The discussion focuses on calculating the velocity and position of a bus given its acceleration function a(t) = 1.13t m/s³. For Part A, the correct approach to find the bus's velocity at time t_2 = 2.15 s, starting from an initial velocity of 4.93 m/s at t_1 = 1.01 s, involves using the equation Vf = Vo + a(tf - to) with the appropriate time difference. For Part B, to determine the position at t_2, a different kinematic equation must be applied, emphasizing the need to account for the time interval when calculating changes in position.
