Question

Q28: For the rear wheel drive car, consider a situation in which the car starts from rest and accelerates to the left. The tires do not slip on the road. Assume the normal force on the front tires is Nfront and the coefficients of static and kinetic friction are Hs and uk, respectively The friction force, Ffront, on the front tires is given by what expression and what is its direction? O Not enough information is given Front HyNront to the left Ffront H&Nfront; to the right 0 Ffront--A,Nfrort to the right Ffront HNfront to the left

Explanation / Answer

Answer: 4th option

Ffront<= Us*Nfront and to the right

As the rear wheel tries to push the car and thus the front wheel forward, the static friction force between the front wheel and tyre doesn't allow the front wheel to slide, and therefore it rotates counterclockwise under the action of static friction will act to the right, so that wheel rotates counterclockwise.
