Q1. A bus travelling along the straight road at 100km/hr-1 and the bus conductor make at 6kmhr-1 on the floor of the bus in the same direction on the bus. Find the speed of the conductor relative to road and relative to the bus. If the bus conductor now makes at the same rate but in opposite direction as the bus. Find his new speed relative to the road.

Q2. A loudspeaker of mass 17.0 {rm kg} is suspended the distance of h = 1.70 {rm m} below the ceiling by two cables that make equal angles with ceiling. Each cable has the length of l = 2.70 {rm m}. What is the tension T in each of the cables? Use 9.80 {rm m/s} ^2 for the magnitude of the acceleration due to gravity.
