Imagine that a small bug is trapped between two blocks ( 10kg and 5kg) In each case a person applies a force of 150 N to the right, but the order of the blocks is reversed. In which case will the bug have a better chance of surviving? Calculate the force acting on the bug in each case?
The bug must apply the force necessary to accelerate, or overcome the friction of, the block in front of it (in the direction of motion). The lighter that block is, the less the bug is stressed.
Two blocks are connected by a very light string passing over a massless and frictionless pulley (the figure ). Traveling at constant speed, the 20.0- block moves 80.0 to the right and the 12.0- block moves 80.0 downward
