Haha sorry, I'm still very new to Physics, as I'm only 13. Our teacher just started teaching us, but he's far from thorough so we're struggling...
For the FBD, I drew
1) weight acting vertically downwards
2) friction acting opposite the direction of motion
3) a force acting perpendicular...
Well, as stated in the title, I used F=ma, so the working I came up with was F=24x0, with 24 being the mass of the box and 0 for the acceleration since the speed is constant.
Homework Statement
A 24kg box is placed on a rough slope. Determine the magnitude of the frictional force exerted by the slope on the box if the box is moving downward at a constant velocity of 9.0m/s. The slope incline is 40°
Homework Equations
F=ma
The Attempt at a Solution
F = 24 x 0
