1. my teacher randomly pulled out this equation and im having trouble understanding what exactly its use is and how to apply it. i think it refers to velocity on an inclined plane but idk

gravity x sin (theta) x time = velocity

any help?
2. Its using M1, but the force acting down an inclined plane on a body of mass m is mg sin(theta). Since F=ma, a=g*sin(theta). Using v=u+at where u=0, speed at a given time t is g*sin(theta)*t.
Hope this helped
