3 as a single number is considered a sf
D, you wanna know why.... cause I looked it up
The north and south forces have no effect on the east and west forces.
We can handle the two groups separately.
(20N south) + (30N north)
= (20N south) + (20N north + 10N north)
= 10N north .
(40N east) + (50N west)
= (40N east) + (40N west + 10N west)
= 10N west .
Increasing the level of an incline:
Increases final velocity
Increases the work done
Increases the initial potential energy
Increases the final kinetic energy
I believe it is acceleration
