ACTIVITY 1.2 Solve the following work problems: 1. A crate of mass 50kg is pushed along a floor with a force of 20N for a distance of 5m. Calculate the work done. 2. How much work is done when a 4kg package is pushed by a horizontal force of 10N to a distance of 5m along a level floor, friction being neglected. 3. How much force is applied if the work done to push a 35 kg box at a distance of 8.0 meters is 383J down the hallway at a constant speed? 4. How much work is done by you when apply a horizontal force of 48 N to push a 35 kg box 8.0 meters down the hallway at a constant speed? 5. An object has been moved at a distance of 150cm. If the work done on the object is 350J, how much force is applied in order to mo ove th​
