"What is the acceleration of a car of mass 1200kg, when the driving force on it is 4000N and the total frictional force on it is 900N?
What is the acceleration of this car climbing a hill with a gradient of 8 degrees?"
I got the first part, as obviously a= f/m, resultant force is 3100, and 3100/1200 = 2.6 ms^-2.
But I'm really not sure how to approach the second part...can anyone give me some clues??
Thanks!
