Question

Find out kinetic energy of car of mass 300 kg moving with constant velocity of 60km/hr

Answer 1

Answer:

Kinetic Energy = 41666.67 J

Explanation:

Given that,

Mass = m = 300kg

Velocity = v = 60 km/hr = 60 * 5/18 = 50/3 m/s

We know that,

Kinetic Energy = KE

$\boxed{KE = \frac{1}{2}mv^{2} }$

Putting the values in we get,

KE = 1/2 * 300 * (50/3)²

KE = 1/2 * 300 * 2500/9

KE = 41666.67 J
