(b) At 4.2 seconds after noon both blocks were at rest at the positions given above. At 4.4 seconds after noon, what is the (vector) momentum of block 2?
kg · m/s
(c) At 4.4 seconds after noon, what is the (vector) momentum of block 1?
kg · m/s
At 4.4 seconds after noon, which one of the following statements is true?
Block 2 is moving faster than block 1.
Block 1 and block 2 have the same speed.
Block 1 is moving faster than block 2.
Though the force clearly changes as the object move, what simplifying assumptions can we make that make the problem manageable? What does Newton's Third Law relate?
