A pulley-block system is used for testing in a UHart mechanics lab. The pulley has an outer radius of R = 0.75 m, an inner radius of 0.44 m, a mass-moment of inertia of IG = 7.5 kg*m2 , and is constrained to rotate about its mass center G. The inner radius has a cord wrapped around it that is used to pull the block, which has a mass of 5.8 kg. The coefficient of friction µ between the block and the surface is 0.37. A second cord wound around the outer radius of the pulley is pulled down with a constant force F of 22 N which starts the system from rest. There is no slip between the cords and the pulley. (a)(15 points) Draw the FBD and the MAD for the system, showing all forces and resulting motions, (b) (20 points) Determine the angular velocity ω of the pulley after 5 seconds.

answer: 500 wph.

explanation:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?
