(Q1) A 50kg boy suspends himself from a point on a rope tied horizontally between 2 vertical poles. the 2 secments of the rope are then inclined at angles 30degrees and 60degrees respectively to the horizontal. The tension in the sefments of the rope is (a)25.0 and 43.3(b)50.0...

Last physics help question (my thoughts given)
A 160-N child sits on a light swing and is pulled back and held with a horizontal force of 100N. The tension force of each of the two supporting ropes is: a) 60N b) 94N c) 120N d) 190N e) 260N work: weight is down, the pull is back, so the tension must act at an angle to ...
