Fig. 1.1 shows the speed-time graph for a car.
At time , the brakes are applied and the car comes to rest with uniform deceleration.
State the speed of the car just before the brakes are applied.
speed = ______
Explain what is meant by uniform deceleration.
A lorry travels at a constant speed of for . At time , the brakes are applied and the lorry slows down with the same deceleration as the car.
On Fig. 1.1, draw the speed-time graph for the lorry.
Explain how your graph shows that, while braking, the lorry travels further than the car.
