1. The problem statement, all variables and given/known data The block shown in Fig. 4-48 lies on a smooth plane tilted at an angle = 25.0 degrees to the horizontal. Ignore Friction. Determine the acceleration of the block as it slides down the plane. Picture: http://img504.imageshack.us/my.php?image=webassignplanesa0.jpg 2. Relevant equations 3. The attempt at a solution Our teacher taught us to solve the problem by using right triangle trig, SOHCAHTOA etc, but I can't do that since I don't have enough information... Does anyone know how I can begin this?
