Problem 44GP

A 1500 kg car takes a 50-m-radius unbanked curve at 15 m/s. What is the size of the friction force on the car?

Step-by-Step Solution:

Solution Step 1 of 3 Centripetal force is the force that acts on a body which is moving in the circular path and it is directed towards the center of the circular path on which the body is moving, as in the figure below;here as the car is moving in the curve Centripetal force(F) of an car under uniform circular motion is given by equation 2 F c mv /r Where m and v are the mass and velocity of the car, r is the radius. Step 2 of 3 Static friction is the opposition offered for the applied force on an object, to keep the object at rest. At the start, when we push a block, we experience an opposition that is offered by static frictional force. Once the static frictional force is overcome, then we experience kinetic friction in motion. When the car is moving in the curve or circle, the centripetal acceleration will be due to the static force that is acting on the tire, due to the instantaneous contact of tire with the road, because which there will be no sliding or skidding of tires during turning in the curves. As shown in figure below, Centripetal force(F )= statcc frictional force(F ) s
