The plank is 3.6 metres long. It is being used as a lever to lift a 40-kilogram box. This represents a load of 400 newtons. (a) If the fulcrum were placed in the centre of the plank, what downward effort would the man on the right need to apply to raise the box? (b) If the man...
A building with a weight of 5.200e+7 N is built on a concrete foundation with an area of 1300 m2 and an (uncompressed) height of 2.82 m. By what vertical distance does the foundation compress?
Bob and Ray push on a door from opposite sides. They both push perpendicular to the door. Bob pushes 0.63 m from the door hinge with a force of 89 N. Ray pushes 0.57 m from the door hinge with a force of 98 N, in a manner that tends to turn the door in a clockwise direction. W...
A motor lifts a 70.0 kg box off the ground, starting from rest. In 8.00 seconds it lifts the box to a height of 20.0 m. At that time, the box is moving upward with a velocity of 5.00 m/s. What is the average power of the motor during this time interval?
