(adsbygoogle = window.adsbygoogle || []).push({}); A box, mass 100kg, must be pushed onto a table using an inclined plane 1.5 m high. The plane is 4 m long. If the pleane offers a frictional force equivalent to 10% the weight of the box, what force must be applied to move the box?

What I tried:

sin^-1(4/1.5) = 22.6

100 * 9.8 = 980 N (fgrav)

980cos22.6=904.77N (Fperpendicular)

Ffrict=10%980=98N

That's where I get stuck. I'm not sure if I'm even doing it right (However, I know the angle is).

Please help. My exam is tomorrow.
