Question

Calculate the kinetic energy of abody

of mass 5kg moving with
Velocity of
a
3mls-​

Answer 1

The kinetic energy is 22.5J .

Step-by-step explanation:

Assuming that the formula to find kinetic energy is K.E = 1/2×m×v² where m represents the mass and v is the speed. Then, you have to substitute it :

`k.e = (1)/(2) * m * {v}^(2)`

`let \: m = 5,v = 3`

`k.e = (1)/(2) * 5 * {3}^(2)`

`k.e = (1)/(2) * 5 * 9`

`k.e = (1)/(2) * 45`

`k.e = 22.5 \: joules`

(Correct me if I am wrong)
