Two blocks collide on a frictionless surface. After the collision, the blocks sticktogether. Block A has a mass M and is initially moving to the right at speed v. Block B has amass 2M and is initially at rest. System C is composed of both blocks. (a) Draw a free-bodydiagram for each block at an instant during the collision. (b) Rank the magnitudes of thehorizontal forces in your diagram. Explain your reasoning. (c) Calculate the change inmomentum of block A, block B, and system C. Anybody want to take a crack at this?

Asuppose a suitcase has a mass of (m) 30 kg and a net force (n) of 10 kg*m/s. what is the acceleration rate of the suitcasein m/s? show your work to support your answer.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
