A small body of mass m swings in a vertical circle at the end of a cord of length R. If the cord makes an angle of 0 = 37° with the vertical, then the tangential acceleration as of the body is given by: 1 1 137, RRT m mg an O Tan Octano OD RECORD OS
A roller coaster car of mass m 20 kg is moving inside a circular path of radius R=5 m with a constant speed of 10 ma's. The normal force in (N)acting on the car by the track at the top point is Oa 1800 1.900 OC 600 Od 300 O. 200
A 10 kg block on a 37° rough incline is held at rest by a force F. as shown. If the coefficient of static fric- tion between the block and the surface is =0.1, then the minimum value of Fin N required to keep the block at rest is: m H 37 a 52 Ob 20 Oc44 od 36 O e 28
