A 1450kg car drives toward a 60kg shopping cart that has a velocity of -1.2m/s towards the car. The two objects collide, giving the car a final velocity of 5.13m/s, and the shopping cart a velocity of 11.75m/s. What is the initial velocity of the CAR? A. -5.36 m/s
B. 5.67 m/s
C. -5.67 m/s
D. 5.36 m/s

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
