A pulley system is used to lift a 52kg crate. One chainconnects the upper pulley to the ceiling, and the secondchain connects the lower pulley to the crate. The crateis raising with an acceleration of 2.0 m/s^2. Assuming the masses of the chains, pulleys, and ropes are negligible, determinethe magnitude of the force. (The direction of force is downward). Determine the tension in the upper chain. Determine the tension in the lower chain.
