SINGLE CORRECT ANSWER TYPE1. The bob of a simple pendulum (mass m and length D)dropped from a horizontal position strikes a block of thesame mass elastically placed on a horizontal frictionlesstable. The KE of the block will be(a) 2 mgl(e) mgl(b) mgl/2(d) 02, From a stationarv tonk of mass 125000 pound a small shell

Answer»

when the bob is a height l then it potential energy = m g lIt hits another block of same mass.So as per conservation of energym g l will be equally distributed among the two.Hence kinetic energy of block will be1/2 * m g l
