Two 10 kilogram boxes are connected by a massless frictionless pulley. The boxes remain st rest with the one on the right hanging vertically and the one on the left 2.0 meters from the bottom of an inclined plane that makes an angle of 60 degrees with the horizontal. The coefficients of kinetic friction and static friction between the left hand box and the plane are 0.15 and 0.30 respectively. You may use g= 10 m/s(2nd power), sin 60 degrees = .087, and cos 60 degrees = 0.50.
What is the tension in the string
What is the force/ forces on the box that is on the plane
