A heavy box of mass “n” kg slides 12.0 m along a straight friction less 30 degree incline. If
the box starts from rest at the top of the incline, what is its speed at the bottom. (hint: think
energy)
I used Fd=1/2mv^2 which was msin30(12)=1-2mv^2 and I canceled the masses then came out with velocity=3.5m/s
