Question

The kinetic energy of a car is 40 kJ. What is the
velocity of the car if its mass is 10,000 kg?
Ans: 2.8 ms 1​

Answer 1

Answer:

Answer is 2.8m/sec by using formula mv^2/2

Answer 2

Hii its tom85

kinetic energy=mv^2/2

m =10,000

k.E= 40000j

v = sqrt k.E/m

v= sqrt40000/10,000

v=2m/s

dude i think your answer is wrong
