Question1
Find out the tension in each of the two ropes supporting a hammock if one is at an angle of = 14 above horizontal and the other is at an angle of = 38 above horizontal. The person sleeping in the hammock (unconcerned about tensions and ropes) has a mass of 65.
Question2
A 8.5 {rm kg} dog takes a nap in a canoe and wakes up to find out the canoe has drifted out onto the lake but now is stationary. He walks along length of the canoe at 0.55 {rm m/s}, relative to the water, and the canoe simultaneously moves in the opposite direction at 0.19 {rm m/s}.
Question3
