Q The only force F acting on a 2 kg body moves along x-axis varies as shown in the figure. The velocity of the body along positive x-axis at x=0 is 4m/s. The kinetic energy of the body at x=3 m is:- 1) 4 J 2)8 J 3)12 J 4)16 J Share with your friends Share 19 Shobhit Mittal answered this Dear Student, work done by force F in 3 sec =-4J from the area under the curve .initial KE=2*162=16 J final KE=16J-4J=12Joption 3 regards 13 View Full Answer
