Question

Calculate the Kinetic Energy when the mass of the car is 1,200kg and the speed
is 2.78 m/s. ​

Answer 1

Kinetic energy of the car = 4637.04 J

Step-by-step explanation:

Mass of the car (m) =1200 kg

speed of the car (v) = 2.78 m/sec

Kinetic energy =
`(1)/(2)mv^(2)`

Putting the values of m and v,

Hence, Kinetic Energy of the car =
`(1)/(2)1200\cdot 2.78^(2)` = 4637.04 J
