4. A car is moving along straight-line path with speed of 16 m/s. After 10 seconds the driver applies brake to stop the car in 5 seconds. Determine total distance the car moves during this 15 second time interval.
A car travelling on a straight road starts from rest and accelerates at 2.0 m/s2 until it reaches a speed of 20 m/s.
