Question

Illustration 2
Kinetic energy of a particle moving along elliptical
trajectory is given by K=as2 where is the distance
travelled by the particle. Determine dimensions
of a.​

Answer 1

k= a s^2

as total energy is 1/2 k A^2 so to determine the dimension it would be same

k= w^2 m

= T^-2 M

So dimension of a is M T^-2
