Learning Goal: Once you have decided to solve a problem using Newton's 2nd law, there are steps that will lead you to a solution. One such prescription is the following: • Visualize the problem and identify special cases. • Isolate each body and draw the forces acting on it. • Choose a coordinate system for each body. . Apply Newton's 2nd law to each body. • Write equations for the constraints and other given information. • Solve the resulting equations symbolically. • Check that your answer has the correct dimensions and satisfies special cases. • If numbers are given in the problem, plug them in and check that the answer makes sense. • Think about generalizations or simplifications of the problem. As an example, we will apply this procedure to find the acceleration of a block of mass m2 that is pulled up a frictionless plane inclined at angle with respect to the horizontal by a massless string that passes over a massless, frictionless pulley to a block of mass m₁ that is hanging…

Learning Objectives: In this assignment students will use Newton’s laws and solvesystems of symbolic equations to find quantities of motion such as position, velocity,acceleration and time. Students will represent information in multiple ways. Studentswill make predictions and assess their work.Problem Statement: An object of mass m rests at the top of a smooth slope ofheight h, length L and angle ?. The coefficient of kinetic friction ??. A very smallpush overcomes static friction, and the object begins to slide down the slope.Using your knowledge of kinematics, determine a symbolic expression for the object’sspeed when it reaches the bottom of the hill. This should be in terms of some of all ofgiven/known variables m, h, L, g, ? and ??. Check the physical units of yourexpression.

There must be a diagram/drawing. • You must list any resources used to solve the problem (books, websites, tutoring, and any other people you worked with) on the first/front page. Problem 1 Two blocks, one of mass m₁ = 3.0 kg and the other of mass m₂ = 9.0 kg, are slung over a pulley by a massless rope, as depicted in the figure. Initially, the masses are at the same height. The pulley is a uniform solid disk with a mass of M = 36.0 kg and a radius R = 10.0 cm. The total length of the rope, including the part slung over the pulley, is L= 4.0 m. The masses are I released from rest at time t = 0 sec. A. How much time does it take for the pulley to complete one revolution? B. At what time will the smaller mass crash into the pulley? (Assume the mass is much smaller than the pulley for simplicity.)
Application I. Direction: Solve the following problem. Put your answer on a separate sheet. 1. A piece of equipment weigh 539 N and 209 N on Earth and Mars, respectively. What is the acceleration due to gravity on the surface of the Mars? 2. Two forces of magnitudes 6.0 N and 4.0 N act on a 3.2 kg body. What is the acceleration produced when these forces are acting in the same direction? What is the acceleration produced when these forces are oppositely directed?
Aliyah is solving a physics problem involving an elevator. She draws the (unlabeled) force diagram for the elevator show on the right and says "this force diagram could represent an elevator moving upwards." José disagrees. Looking at the force diagram he says "the way you've drawn the force diagram the elevator CANNOT be moving upwards. It MUST be moving downwards because the force pointing down is bigger than the force pointing up." (a) Correctly label the force diagram. (b) Who do you agree with and why? For the statement you disagree with, how would you convince him/her that he/she is incorrect?
