Answer» What is RELATIVE velocity?Relative velocity is measured in a frame where an object is either at rest or moving with respect to the absolute frame.A body starts to move from rest and gains ACCELERATION of 2m/s2 in 30 sec. Find the final velocity.u=0 a=2m/S 2 t=10Second S 1 =ut+0.5at 2 s 1 =0+0.5×2×100=100m S 2 =v+2 v=u+at=0+20=20m/s s 2 =20×30=600 m 0 2 −v 2 =2(−a)s 3 s 3 = 8 400 =50m s=s 1 +s 2 +s 3 =100+600+50=750Hope this helps you DEAR |
