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?(adsbygoogle = window.adsbygoogle || []).push({});

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.
