A 3.3 kg wooden block is placed on 22 degree inclined plane and is connected by a string that passes over a light friciton less pulley at the top of the incline and then attached to a hanging 3.0kg block.If the coefficient of static friction bet the 1st block and the surface of the plane is 0.25 and coefficient of kinetic friction is 0.15
a)which direction will the first block move, up the plane or down the plane if it does.
b)Calculate the acceleration of the system and the tension force in the string.
