1. Suppose you are standing on a weighing scale in an elevator. What is the reading on the scale when you are (a) accelerating upward and (b) accelerating downward at a arte of 2.0 m/s?? Your mass is 50.0 kg. Bough o frictionless pulley

I would like to know how to set up a free body diagram for this problem and know what formula I can use to find an expression for part b

Draw a free body diagram of an object on a ramp and analyze the forces. Explain why the slope of the ramp can be used to determine the coefficient of friction. Use math to expalin your answer.

Block 1 (9 kg) is located on the surface of a table. A hand pushes horizontally to the right on block 1 with a normal force of 108 N. The coefficient of kinetic friction between the block and the surface equals 0.8.On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram, enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component.FORCES on BLOCK 1Weight force on block 1 by Earth  W1E =  i +  j N Normal force on block 1 by Surface  N1S =  i +  j N Normal force on block 1 by Hand  N1H =  i +  j N Frictional force on block 1 by Surface  f1S =  i +  j N  What is the acceleration a of block 1?a =  i +  j m/s2

Consider the system in the picture below: a cart of mass M with a static friction coefficient u is connected through a massless string to a hanging mass m. M is a capital letter, m is lower case. Write them as such, or vour equations will be confusing, M We want to find the maximum value of the hanging mass m such that the system is in equilibrium. 1. Free body diagram (FBD): Draw a FBD for each: the Cart and the hanging mass. Clearly show all the forces. 2. Clearly write the equilibrium equations for the cart in the horizontal and vertical direction. 3. Clearly write the equilibrium equation for the hanging mass. 4. Solve the system of the three equations above for the hanging mass m. Show your calculation to get credit. 5. What would happen if mass m exceeds this value? Explain.

Crate A hangs from a cable C and rests against the wall, so that the cable makes an angle with the wall. Draw a complete free-body diagram of crate A. Include labeledangle(s), in terms of ?, for any force(s) that are at an angle (not purely horizontal or vertical).
