i've posted this before, but i really don't get how to do it because we never learned this, so if someone would tell me how or just do the first one or something, i would appreciate it. thanks.

Determine the units of the quantity described by the following combinations of units:

a. kg (m/s)(1/s)

b. (kg/s) (m/s^2)

c. (kg/s)(m/s)^2

d. (kg/s)(m/s)

Just multiply out the dimensions as if you were multiplying fractions and coefficients

a. kg (m/s)(1/s) = kg m/s^2

This is the same as mass x acceleration (force), and has the special name of Newtons.

The same applies to part (d)

c. (kg/s)(m/s)^2 = [kg (m/s)^2]/s = Joules/s
