Work = Change in kinetic energy = 0.5 m (v^2 - u^2)= 0.5 x 1500 kg x [(60 x 5/18 m/s)^2 - (30 x 5/18 m/s)^2]= 156250 joules= 156.25 kJ

WOrk dOne increase the velOcity of Car = change in Kinetic EnargY W = 1/2 m ( v^2 - u^2) mass :: 1500 kg u= 30 km/h ( 30×5/18)m/s = 25/3 m/s v = 60km/h. ( 60×5/18) m/s = 50/3 m/s. plug- in equation these ValUe we get,W = (0.5) (1500) (625/9) (4-1) = 156250 J. = 156.25 J ThanKs :::::
