PHYS 02LA Study Guide - Final Guide: Impala, Net Force, Maximum Force
Document Summary
Prepare: we will use the particle model for the object and use newton"s second law. Assume that the maximum force the road exerts on the car is the same in both cases. Solve: use primed quantities for the case with the four new passengers and unprimed quantities for the original case with just the driver. The original mass was 1200 kg and the new mass is 1600 kg. Assess: we expected the maximum acceleration to be less with the passengers than with the driver only. Prepare: knowing that for every action there is an equal and opposite reaction and that these forces are exerted on different objects, we can identify, draw and label all the action-reaction pairs. Knowing all the forces acting on skater 2, we can construct a free-body diagram for skater 2. Figure (i) shows all three skaters and the action/reaction forces between them.
