A block is pushed up a ramp and is observed to accelerate up the block as is shown in the figure below. The friction coefficient between the block and the ramp is mu. Write an expression for the acceleration of the block in terms of F, theta, m, g and mu.
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?
