| vikash | Re: scra sample paper pdf download As you want here I am giving below UPSC Special Class Railway Apprentices' (SCRA) exam sample paper on your demand : 1. A simple of mass m is at x=0 and moving along the x axis with velocity V0, at time t=0. it is subjected to a frictional force -bvx where b is a constant. and vx is the velocity in the x-direction. At what position x on the x-axis will it come to rest ? (a) x=bv (b) x=bv/m (c) x=mbv (d) x=mv/b 5. A body B of mass m moving forward with velocity v along the x-axis, collides elastically with a stationary object C of mass 2m at the origin. After the collision, body B moves backward along the x-axis. Given that the kinetic energy of the system is conserved. what is the speed of the object C after the collistion ? (a) 2v/3 (b) v/2 (c) v/3 (d) 3v/4 6. A body is moved along a straight line by a machine delivering constant power. The distance moved by the body in time t is proportional to (a) t 1/2 (b) t 3/4 (c) t 3/2 (d) t2 7. A body of mass 3 kg is under a force which causes displacement in it, given by s=t2/3 in meter, with time t in second. what is the work done by the force between time t=0 and t=2 ? (a) 8 J (b) 5.2 J (c) 3.9 J (d) 2.6 j UPSC Special Class Railway Apprentices' (SCRA) exam sample paper     |
