Question

a object of mass 200g moving with velocity 50cm/s what is kinetic energy​

Answer 1

Answer:

Explanation:we know that k.e=1/2×m×v^2

Therefore = 1/2×200×(50)^2

=100×2500

=250000

Answer 2

We know That Kinetic Energy=1/2x mass x (velocity)²;

K.e=1/2x200x50²

=100x50²

=100x2500

=250000g cm / s
