Draw a free body diagram (fbd) for m1 for the case where it is released from rest. Use the notation shown in class, F 2on 1. Draw your force vectors to scale so you can tell the direction of m1’s acceleration is to the right. Clearly indicate which direction you are choosing as positive for the horizontal and vertical directions. Write out the two equations from Newton’s Second Law (F = ma), one for each direction. Denote your x-equation as equation (1) and your y-equation as equation (2). No need to solve for anything just yet.
Use your fbd diagram of m1 to determine which force and which object is trying to horizontally accelerate m1. Which force and which object is trying to prevent this acceleration? Which of these two forces is larger?
Draw a fbd for m2. Clearly indicate which direction you are choosing as positive for the vertical direction. Also be sure that the force vector arrows are drawn to scale so that you can tell that m2 is accelerating down. Use Newton’s Second Law to…

- 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?

He is to draw a free body diagram for a man walking to the left and comes up with the following: He reasons, “The man is walking to the left, so the force of friction is acting in the opposite direction. The normal force should be opposite and equal to that of the gravitational force.” Is Tommy correct with his diagram and reasoning? If so, explain. If not, what mistake did he make?
