A car is travelling along a straight road at 8.0 m/s.
The driver presses the accelerator and the velocity of the car increases to 20 m/s in 6.0 s.
Write down the equation linking acceleration, change in velocity and time taken.
Calculate the acceleration of the car.
Give the unit.
Later, the car slows down from 20 m/s and stops. The deceleration of the car is 2.5 m/s2.
Calculate the time taken for the car to stop.
State what is meant by deceleration.
