A helium balloon floats at the end of a string. The net force (the bouyancy force minus the weight) on the balloon is 33 N. If the tension in the string exceeds 54 N of force, the string will break. How great a force can a horizontal wind exert on the balloon before the string breaks?
You work for a moving company are forced to pull two crates along the floor as shown in the figure below. The two crates are connected by a very light rope (it's mass is much smaller than that of either block). You want to get done as soon as possible and pull as hard as you possibly can and manage to maintain a pulling force of F=600.0 N. As a result the crates are moving with an unknown constant acceleration a. Their masses 50.0 kg and m = 20.0 kg, and the coefficient of kinetic friction between each crate and the floor is are mi H =0.300. g=9.81 m/s m2 F

A block and a ball are connected by a string as shown in the figure. The block sits on a level, rough surface. The coefficient of static friction between the block and the surface is μ = 0.841.

You are camping in bear country and you are setting up your camp for the night. You string up your food, as shown in the picture below, so that the bears in the area do not steal it. The breaking tension of the type of string you are using is 800 Newtons. Any tension greater than that will cause the string to snap. The mass of your food pack is 10 kg. If a bear comes along in the night and pulls straight down on the food pack, with what maximum force can it pull before the strings snap?
