Q1. A curve of radius 152 m is banked at an angle of 9°. An 808 kg car negotiates the curve at 37 km/h without skidding. Neglect the effects of air drag and rolling friction. Find the following.

(a) The normal force exerted by the pavement on the tires

(b) the frictional force exerted by the pavement on the tires

Q2. A stick with a mass of 0.234 {rm kg} and length of 0.426 {rm m} rests in contact with a bowling ball and rough floor. The bowling ball has a diameter of 20.6 {rm cm}, and the angle the stick makes with the horizontal is 30.0 {rm ^circ}. You may suppose there is no friction between the stick and the bowling ball, though friction with the floor must be taken into account. Find out the magnitude of the force exerted on the stick by bowling ball.
