Question

Calculate the Kinetic Energy when the mass of the car is 1,200kg and the speed
is 11.11 m/s. ​

Answer 1

74059.26J

Explanation

Formula

EK=mv^/2

m=1200kg

v=11.11m/s

E=1200kg×(11.11m/s)^/2

E=74059.26J

Answer 2

74059.3 J

Explanation:

KE = I/2mv²

KE = 1/2(1200)(11.11)²

KE = 1/2(1200)(123.4321)

KE = 74059.26 J
