A motorcycle moves from rest and accelerates uniformly on a straight road, reaching a speed of 25 ms in 20 s and then moves at a constant speed of 25 ms1 for a distance of 300 m. Determine the total displacement for the entire trip.

Acar travels along a highway with a velocity of 24 m/s, west. the car exits the highway; and 4.0 s later, its instantaneous velocity is 16 m/s, 45° north of west. what is the magnitude of the average acceleration of the car during the four-second interval?
