Question

calculate kinetic energy of car mass 1000 kg running with velocity 54km/hr​

Answer 1

Answer:

mass= 1000kg

v= 54km/h= 15m/s

K.E= mv^2/2

    = 1000x15x15/2

    =500x225= 112500 J

ohaiyo!

Answer 2

Answer:

Given,

Mass (m) = 1000 kg

Velocity (v) = 54 km/hr

= (54*5)/18 m/s

= 15 m/s

K.E = 0.5mv²

= 0.5*1000*15*15 J

= 112500 J

or,

= 112.5 kJ

The Kinetic Energy of Car is 112500 J or, 112.5 kJ.

Hope this helps!
