Answer:

8kg

Explanation:

Kinetic energy = 1/2 mv^2

Where

M = mass

V = speed or velocity

Given

Kinetic energy = 36

V = 3m/s

Therefore

36 = 1/2 x m x 3^2

36 = 1/2 x m x 3 x 3

Multiply through

36 = m x 9 /2

Cross multiply

36 x 2 = m x 9

72 = m x 9

Divide both sides by 9

72/9 = m x 9/9

8 = m

m = 8kg
