Q1. A 28 kg loudspeaker is suspended 3.0 m below the ceiling by two cables that are each 64 degrees from vertical. What is a tension of the cable?
Q2. Two boats start together and race across a 56-km-wide lake and back. Boat A goes across at 52 km/h and returns at 56 km/h. Boat B goes across at 36 km/h, and its crew, realizing how far behind it is getting, returns at 79 km/h. Turnaround times are negligible, and boat that completes the round-trip first wins.
