K.C.S.E Physics Q & A - MODEL 1998PP1QN29

Fig. 8 shows a car of mass M moving along a curved part of the road with a constant speed.

Explain the fact that the car is more likely to slide at B than at A if the speed is not changed.

ANSWER

• Since F=MV2/V the sharper the corner (as B) the small the value of R hence the greater the F. (M& V constant).
