Question1
A curve of radius 160 m is banked at an angle of 11°. An 808-kg car negotiates the curve at 88 km/h without skidding. Ignore the effects of air drag and rolling friction. Find out the following points.
(a) The normal force exerted by the pavement on the tires
(b) the frictional force exerted by the pavement on the tires
Question2
An 26 g rifle bullet traveling 370 m/s buries itself in a 4.8 kg pendulum hanging on a 2.6 m long string, which makes the pendulum swing upward in an arc. Determine the greatest vertical displacement of the pendulum (height). (g = 9.8 m/s2)
