Question

A moving body of mass 0.3 kg has 60 J of kinetic energy. Calculate the speed of the body.
what is the answer​

Answer 1

Answer:

20m/s

Explanation:

Given data:

mass= 0.3kg

kinetic energy= 60J

To find: speed of body= ?

Solution=

60= 1/2 x 0.3 x v^2

v^2= 120/ 0.3

v= 20m/s

( If u have any problem, solve with calculator)
