Written Problem [Individual]. Write a Jlly worked solution on your Written Problem Answer Sheet. An man of mass 95 kg is skating northward and happens to suddenly collide with a boy of mass 25 kg who is ice skating toward the east and hangs onto him to keep from falling. Immediately after the collision, the two are moving together at 3.2 m/s in a direction 54 north of east. How fast was the boy moving just before the collision? 3. . Sketch and translate Sketch the process described in the problem statement. Label the physical quantities and identify unknowns. If you are using Newton's laws or the work-energy principle, choose an appropriate system. . Sim If and die ram Identify what simplifying assumptions are necessary to solve the problem. If you are using Newton's laws, construct a force diagram for the system. Choose appropriate coordinate axes. If you are using the workenergy principle, construct an energy bar chart. Specify where the zeros for potential energies are. assess the impact on your final answer if you changed one of your assumptions. Represent mathematically Use the force diagram to apply Newton's second law to the situation, or use the energy bar chart to apply the generalized workenergy equation. If necessary, use kinematics equations to describe the motion of the object. Do not plug in numbers in this step. Solve and evaluate Rearrange the equation and solve for the unknown quantity. Substitute known values for variables in your expression and include units. (Include units in every step after this.) Clearly indicate your final answer. Verify that your answer is reasonable with respect to sign, unit, and magnitude. Explicitly verify that your units worked. Evaluate the answer in one of several ways such as (but not limited to) one of the following: assess the reasonableness of the magnitude of your answer; take various limits of the input values and assess whether they change your final answer in a reasonable way; assess the impact on your final answer if you changed one of your assumptions
