Q. State the maximum height in terms of a, t_1, and/or g. Note that in this problem, g is a positive number equal to the magnitude of the acceleration due to gravity.
Q. A plane flies from base camp to Lake A, a distance of 320km at a direction of 20.0° north of east. After dropping off supplies, plane flies to Lake B, that is 150 km and 30.0° west of north from Lake A. Graphically resolve the distance and direction from Lake B to the base camp.
A loudspeaker of mass 22 {rm kg} is suspended a distance of h = 2 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has the length of l = 3.90 {rm m}.
