The acceleration of the car is equal to -204km/hr
Explanation:
- The initial velocity ,u of the car is equal to 54 kilometre per hour and the final velocity, v, is equal to 36 km per hour.
- The change in the velocity of the the car is equal to - 18 km per hour.
- The time taken t for this change in velocity is equal to 5 minutes or 5/60 hr or 1/12 hr.
- The equation for acceleration is equal to v= u + at.
- Hence a = (v-u)/t
- = (36-54)/(1÷12) = -204km/hr, here the negative sign denotes the deceleration of the car.
