Below are birds-eye views of six identical toy cars moving to the right at 2 . 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 are applied. Rank from largest to...
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 Momentum in Two Dimensions Ranking Task The figures below show bird's-eye views of six automobile crashes an instant before they occur. The automobiles have different masses and incoming velocities as shown. After impact, the automobiles remain joined together and skid to rest in the direction shown by v_final. Rank these crashes according to the angle theta, measured counterclockwise as shown, at which the wreckage initially skids. Rank from largest to smallest. To rank items as equivalent, overlap them.
Normal and Frictional Forces Ranking Task Six boxes held at rest against identical walls. Rank the boxes on the basis of the magnitude of the normal force acting on them. Rank from largest to smallest. To rank items as equivalent, overlap them.
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...
Part A.)Six boxes held at rest against identical walls. Rank the boxes on the basis of the magnitude of the normal force acting on them. Rank from largest to smallest. To rank items as equivalent, overlap them. 1.)130N--->7kg 2.)150N--->1kg 3.)150N--->7kg 4.)120N--->3kg 5.)140N--->5kg 6.)140N--->3kg (Since the boxes are at rest, Newton's 2nd law dictates that the horizontal forces on each box must add up to zero. You can use this information to determine the normal forces. If two boxes are both...
Projectile Motion Ranking TaskSix baseball throws are shown below. In each case, the ball is thrown with speed v at an angle θ from the horizontal. In all cases, the baseball is thrown from the same height H above the ground. Assume for the basis of these rankings that the effects of air resistance are negligible.Part ARank these throws based on the maximum height reached by the ball.Rank from largest to smallest. To rank items as equivalent, overlap them.Part BThis...
