• Show all your work with all details for each question by order.
• Forces and components must be verified.
• A free-body diagram must be verified for each mass if it is required.
• Write the required formulas and equations for each problem

1. Below figure find tension on strings. M2= 3kg my= 1kg mi= 5 kg MK= 0.1 50' 2. Below figure find force between masses while system is being pushing by force of F=80.ON and makes the angle of 20 degrees. Friction coefficient between each mass and surface is 0.2 F=8ON m,=5kg My= 3kg my= 1kg 9-20' MK= 0.2 3. Find apparent weight of a 280.0 Lbs (pound) person when elevator goes up with acceleration of 1.60 m/s2. (b) When elevator goes down with acceleration of 1.60 m/s2. (c) When elevator goes with constant velocity up? Find your answers by pound.(1Lb= 4.44Newton) 4. A box with mass of 75.0 kg slides down on an incline plane with an angle of 150 and at the bottom of incline plane its speed is precisely 90% of what it would have been if the slide had been frictionless. Calculate the coefficient of kinetic friction between the slide and the box
