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.

Problem solving: Show your complete solution for each problem. A light rope is attached to a block with a mass of 6kg that rests on a horizontal, frictionless surface. The horizontal rope passes over a frictionless, massless pulley, and a block of mass m is suspended from the other end. When the blocks are released, the tension in the rope is 18N. (a) draw a free-body diagram for each block. (b) what is the acceleration of the 6-kg block? (c) what is the mass m of the hanging block? (d) using the value of the hanging mass calculated in part c, what would be the acceleration and the tension in the rope if the coefficient of kinetic friction between the 6-kg mass and the horizontal is 0.10?

This is a SINGLE question with 2 parts, please answer them with FORCE DIAGRAM, THIRD LAW PAIR AND CALCULCULATIONS. There is a girl in a ship. The total mass of both is 150kg. She hooks a big fish who's mass is 250kg. The fish pulls the boat in the opposite direction of shore (which is in right direction) at a CONSTANT rate of one m/s. A) there is a wind force of 500 newtons towards shore which is the left direction, and the force of water on the ship is 2000 newtons upwards. What is the force of the big fish? Draw force diagram, third law pair and show calculations. Explain your work. B) now, there is no wind, nor wind force. But everything else is the same. What is the acceleration of the ship? Draw force diagram, third law pair and show calculations. Explain your work.

This question is a short free-response question. Show your work for each part of the question. A person pushes a large block on a horizontal ice surface in a straight line to the right with constant speed, as shown above. The mass of the block is 10kg and frictional forces between the block and the ice are negligible. However, the block has a wide cross-sectional area such that air resistance acting on the block cannot be neglected. The opposite is true for the person: air resistance on the person is negligible, but the person’s shoes do not slip on the ice. The table shows the force exerted by the person on the block for several values of constant speed. (a) A student claims that the data show that the magnitude of the force of air resistance is proportional to the speed of the object, within experimental uncertainty. Use physics principles to explain whether the claim is correct. (b) As the person pushes the block, the person moves with the same constant speed as the block. Consider…

Use the worked example above to help you solve this problem. Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are vli = +25.2 cm/s and v2i = -20.3 cm/s, what are the velocities of the balls after the collision? Assume friction and rotation are unimportant.
