Kinetic energy (k) has dimension kg m2/s2. it can be written in terms of the momentum (p) and mass (m) as k = p^2 / 2m. determine the proper units for momentum using dimensional analysis.

Answer : The units for momentum is, kg.m/s

Explanation : Given,

Dimension of Kinetic Energy (K) =

Dimension of mass (m) = kg

The relation between kinetic energy and momentum will be:

Now put all the dimension in this expression, we get:

The dimensional formula of Kinetic Energy =

The dimensional formula of momentum =

Thus, the units for momentum is, kg.m/s

the answer is b

explanation:

real, smaller and upside-down.   so the answer should be b.
