A car moving at a speed of 36 km/hr is taking a turn ona circular road of radius 50 m. A small wooden plate iskept on the seat with its plane perpendicular to theradius of the circular road (figure 7-E4). A small blockof mass 100 g is kept on the seat which rests againstthe plate. The friction coefficient between the block andthe plate is u = 0-58. (a) Find the normal contact forceexerted by the plate on the block.(b The plate is slowlyturned so that the angle between the normal to the plateand the radius of the road slowly increases. Find theangle at which the block will just start sliding on theplate. Ri |
