a box on a smooth inclined plane with an angle of 20 degrees to the horrizontal. If the inclined plane is 5 m long, how long does it take for the mass to reach the bottom of the inclined plane after the mass is released?
I did sin 20 degrees x 5.0 m = 1.71 m
how do i get the mass from this measurement?
1.71m can't equal mg=w
w=9.8m/s^2*mass
If I could find find (a)accel., then I could use one of the
kinematic equations.
