Hey, I'm not sure how to continue...
Forces of 10N north, 20N eat and 5N south act on an object of mass 4kg. How big is its acceleration and what angle does it make with the force in the eat direction.
The Attempt at a Solution
I drew and free body diagram. Now i'm not sure if its correct to add up all three forces to get the accerlation. Or do i have to figure out the angle through using cos sin ect.
Thanks for your help
