The block shown in figure below lies on a smooth plane tilted at an angle theta = 20.7o to the horizontal.
1. Determine the acceleration of the block as it slides down the plane. Ignore friction. they gave nothing but the angle so im a little confused how im supposed to find anything with just one variable.
2. If the block starts from rest x=9.24m up the plane from its base what will be the blocks speed when it reaches the incline.
