A) A traffic light is hanging from two cables. Cable #1 pulls up and left, making an angle of 25o with the horizontal on the left, and cable #2 pulls up and to the right with a force of 180 N, making an angle of 45o with the horizontal on the right. Find the mass of the traffic light.
B) At the park, a 4 m long seesaw is supported in the middle.A 35 kg child sits at the far left end and a 65 kg child sits somewhere on the right hand side. Find how far the second child is from the center in order to balance the seesaw? (Tip: This is a beam problem, pick a pivot point, prob center, and measure all distances from the pivot point)
