a car is intended to move on a rough road by applying a force of 1000 Newton calculate the force of friction of the car if it starts moving with a constant velocity of 30 km per hour on the road |

Answer» Answer: 1000 N Explanation: As CAR is MOVING with constant velocity , so acceleration of the car is zero. Then net force is EQUAL to zero.Thus the applied force by car is equal and opposite to the frictional force. f - ma = lmg Where, L is coefficient of friction f force applied by car a is the acceleration of the car which is zero m mass of the car lmg = f = 1000 N = friction force
