Question

Magnitude of energy E experienced by a certain moving object with speed V is given by E=Kv2 where K is constant find the dimensions of K

Answer 1

Answer:

E= Kv²

K=E/v²

E=Energy Joule(J) = kg m²/s²

v= Velocity v² = m²/s²

Therefore,

K = kg m²/s²

m²/s²

K = kg

So, dimensions of K = [M¹ L⁰ T⁰]
