safe Generic Man is using a machine made of two pulleys and a rope to lift a safe (mass = 500 kg) as shown in the figure above. The rope and pulleys are massless and the pulleys are frictionless. What is the magnitude of the force that Generic Man must pull with in order to lift the safe with a constant speed? O 4900 N O 1220 N O 9800 N O 2450 N O 3270 NA small car pushes a large truck as shown in the gure below. They are speeding up. Is the force of the car on the truck greater than, less than, or equal to the force of the truck on the car? O greater than 0 less than 0 equal to push M A horizontal push force (magnitude = 100 N) pins a wood block M (mass = 2.00 kg) to the rough surface of a wall as shown in the figure above. The coefficient of static friction between the surface of block M and the wall is 0.500. Block M is in static equilibrium. What is the magnitude of the static friction force that acts on block M ?
