One question in EK1001 physics shows a box on an inclined plane with mass of 2 kg at an angle of 30 degrees to the horizontal. The height of the box is 5 m, and the plane has some distance d. It asks for how long it takes to move the distance d.
delta y = 0.5a (delta t)^2
delta y is 10 m because I used xsin30= 5
Then I used mgsin30 for the acceleration of the box down the plane, and I ended up with an answer of t = square root of 2. However, in the book, it says the answer is 2 s.
