3. A 1.20 m long board of uniform density and mass 9.00 kg is attached to a vertical wall at an angle of 35.0° with respect to the horizontal. A light string is attached to the board 0.300 m from the free end of the board. This string is also attached to the wall and makes an angle of 15.0° with respect to the horizontal as shown. a. What is the tension in the string? T-F=ma Tsin(50) ma Tsino) (9.00) (98) T= Hinge 35⁰ 15⁰ T 50° b. What is the vertical component of the force that the wall exerts on the board? S 3.
