1 two children of weight 200 n left and 250 n right sit at, Ask an Expert

Academics

1) Two children of weight 200 N (left) and 250 N (right) sit at opposite ends of a seesaw that is 10 m long. At what point from left side should it be supported to achieve balance?

2) A force of 15 N acting at an angle of 25 degrees to the horizontal is used to pull a box a distance of 5 m across a floor. How much work is done?

3) A 0.5 kg mass is attached to the end of a 1 m string. The systems whirled in a horizontal circular path. If the maximum tension that the string can withstand is 350 N, what is the maximum speed of the mass if the string is not to break.
