Answer:

m = 20 kg

Step-by-step explanation:

Given that,

The speed of a body, v = 10 m/s

Kinetic energy of the body, K = 1000 J

We need to find the mass of the body. The formula for the kinetic energy of a body is given by :


K=(1)/(2)mv^2\\\\m=(2K)/(v^2)\\\\m=(2* 1000)/((10)^2)\\\\m=20\ kg

So, the mass of the body is equal to 20 kg.
