$\huge \Purple {Question}$

Stopping distance of vehicles : When brakes are applied to a moving vehicle, the distance it travels before stopping is called stopping distance. It is an important factor for road safety and depends on the initial velocity (v0) and the braking capacity, or deceleration that is caused by the braking. A car travelling at speed 72km/hr suddenly applies the brake with the deceleration of 5m/s2. Find the stopping distance of the car.

Answer:

v² - u² = 2as

→ (0)² - (20)² = 2 × (-5) × s

→ - 400 = -10s

Divide with 10 on both sides.

→ -400/10 = -10/10 × s

→ -40 = -s

→ s = 40

Therefore, the stopping distance of the car is 40 m.

Answer:

The stopping distance is the distance that the car travels from the moment that the brakes are applied to the moment that the car stops. This is also called the braking distance. d = u2 20 .
