Question

A stone of mass 200 gram has a kinetic energy of 100 joules Calculate the speed of the moving stone .​

Answer 1

Explanation:

Mass of stone = 0.2 kg

Kinetic energy of stone = 100 J

We know,

Kinetic energy of stone

= 1/2 × m × v^2

=> 0.1 kg × v^2 = 100 kg m^2 / s^2

=> v = √(1000 m^2/s^2)

=> v = 10√10 m/s
