Question

Find out the kinetic energy of
a car of mass 3000 kg moving
with a constant velocity of
60 km/hr.​

Answer 1

Explanation:

v=60km/hr=60×5/18m/s=50/3m/s

since kinetic energy=1/2mv^2

therefore KE=1/2×3000×50/3×50/3=416666.66kgm^2/s^2

Thank you

Hope it helps!

Answer 2

m = 3000 kg

v= 60 km/hr = 60 × 5/18 = 50/3 m/s

Kinetic energy = 1/2 × m × v^2

=>1/2 × 3000 × 50/3 × 50/3

=>500 × 50 × 50/3

=> 416666.666 Joules
