A steel ball of mass 3kg is at rest on a table. An exceptionally strong mustached tamarin enters the room and, noticing the ball on the table, picks up a 2kg ball that someone carelessly left lying around and slides it along the frictionless table toward the stationary ball with a velocity of 7.2m/s. After the balls collide, the 2kg ball moves to the left (up in the diagram you are about to draw) at an angle of 32° and the 3kg ball moves at an angle of 27° to the right (down in the diagram you are about to draw). a. Draw and label a diagram (I told you!) of the system described above, without the monkey in it. What kind of collision is this? b. Without using numbers, write the equation for conservation of momentum for the balls in the x- and y-directions separately. c. Solve the y-equation for velocity v1f, again without using numbers. d. Plug in the numbers to solve your equation in part c for v1f in terms of v2f. Assume m1 is the ball that is thrown. e. Plug your value for v1f into the equation for the momentum in the xdirection from part (b) and solve for v2f. From that result, calculate v1f. f. The 3kg ball strikes, and sticks in a 1.35kg box that slides along a rough part of the table for 0.35m. What kind of collision is this? Using conservation laws, calculate the force of friction between the box and the table. i would appreciate the help i can get to understand the material better.
