Hey...again
can someone plz help me?
A 1000kg car is on a frictionless inclined plane that is at an angle of 15 degrees to the horizontal . what is the minimum force by the breaks on the car so that the car does not begin to roll down the hill?
thankyou

For these questions, it's always good to draw a diagram to visualise it!!
If the explanation isn't clear, just give a shout :)))

Also, I accidentally used 9.8 as acceleration due to gravity (because of spesh). I should've used 10! sorry
-
do u victorian humans not use 9.8?
we use 9.8 in physics in western austrlia....i actually asked another question on here
and someone used 10ms^2 and i spent a whole hour trying to figure out why/how/since when, acceleration was 10...then i called myself stupid and assumed the person rounded?
-
Yeah for VCE physics, we use 10m/s^2. Makes it easier to calculate stuff. I guess we're just lazy?? lmao

oh...haha :)
