Question

How do I compute the following calculation with the different units of energy?

70kg x 9.8m/s^2 x 2m

anonymous · Answer

actually u'll get the unit of energy after the multipliction

anonymous · Answer

kg m/s^2 is the unit of force and 'm' is the unit of displacement

anonymous · Answer

so answer will be (98*14) joule

anonymous · Answer

how did you get 14?

anonymous · Answer

70*2* 9.8 = 140* 9.8 = 14 * 98 =  1372

anonymous · Answer

so, just for my general knowledge as this is my first physics class in college... I can just multiply out the numbers, and then change the symbol accordingly depending on what it is that i'm multiplying? 

I took Bus Calc last semester so i'm used to not being able to combine terms if they aren't the same lol

anonymous · Answer

in this expression 1st term is mas
                           2nd term is acceleration
                           3rd term is displacement
so mass times acceleration is force and frce times displacement is work done...which has the unit of energy
