Conservation of Momentum in Two Dimensions Ranking Task The figures below show bird's-eye views of six...
Velocity from Force Diagram Ranking Task Below are birds-eye views of six identical toy cars moving to the right at 2 m/s. Various forces act on the cars with magnitudes and directions indicated below. All forces act in the horizontal plane and are either parallel or at 45 or 90 degrees to the car's motion. Part A Rank these cars on the basis of their speed a short time (ie. before any car's speed can reach zero) after the forces...
Conservation of Energy Ranking Task Six pendulums of various masses m are released from various heights h above a tabletop, as shown in the figures below. All the pendulums have the same length and are mounted such that at the vertical position their lowest points are the height of the tabletop and just do not strike the tabletop when released. Assume that the size of each bob is negligible. Rank each pendulum on the basis of its initial gravitational potential...
