of 146 km/h?Answer in units of J-k.E= 0.u = 146 km/h = 40.E = 0.5*1930*40.......

A racing car has a mass of 1930 kg.
The acceleration of gravity is 9.8 m/s^2
What is its kinetic energy if it has a speed
of 146 km/h?
Answer in units of J

-

k.E= 0.5 mu^2

u = 146 km/h = 40.6 m/s

E = 0.5*1930*40.6^2 = 1590667 J

==============================

-

266282100 j
speed is 525 m/s other person is wrong
