ok so I have no idea what I'm suppose to do or what this question is even asking me...
determine the units of the quanity described by the following combinations of units:
a. kg (m/s)(l/s)
b. (kg/s)(m/s^2)
c. (kg/s) (m/s)^2
d. (kg/s) (m/s)

a. kg (m/s)(l/s)
this is kg m/s^2
which is mass times acceleration
which is force in Newtons
b. this is Newtons/second, beats me
c. kg m/s^2 * m/s
this is force in Newtons times distance/second
which is work per second
which is power in watts
d. looks the same as a to me 
In each case, you can just multiply the units together to get the "units" of the answer. You can also rewrite kg m/s^2 as Newtons or kg (m/s)^2 as Joules
1. Is the "l" supposed to be liters? or the number 1?
If liters, then the combination is Newtonliters, or 10^3 Joule*m^2
2. N/s
3. J/s
4. N
