1.	A car driver driving at a speed of 90 km per hour applied brakes and bring the car to rest in 20 seconds the acceleration of car
Answer» hat,Initial speed of the CAR, u = 90 km = 90000 mBrakes are applied and BRING the car to rest in 20 secondsTo find,The acceleration of the car.Solution,The change in velocity divided by time taken is called acceleration of an object. It can be given by the FORMULA as follows :So, the acceleration of the car is . Negative SIGN shows that the car is retarding.
