Question

A 2 kg ball is dropped from a height of 10 m. Find its kinetic energy just before hitting the ground. [Take g = 10 m s-2.] ​

Answer 1

Answer:

200Joule

Explanation:

when ball will hit ground all of its potential energy ( at height of 10m) will be converted into kinetic energy

so its kinetic energy =potential energy =mgh=2×10×10=200Joule

where m is mass,h is height
