力學之汽車的摩擦力方向

A car moves around a banked road. The radis is 20m. The blanking angle is 10.

If speed (v=5.88m/s),there be no friction acting on the car along the radial direction.

What is the direction of the friction on the car if the speed of the car is higher than

5.88m/s .explain briefly.

    If the speed of the car is higher than 5.88 m/s, the car tends to slide radially outward. Since friction always opposes motion, it is thus obvious that the direction of friction is pointing radially inward towards the centre of the turn.
