AP Physics Fall Exam questions and answers Graded A+

AP Physics Fall Exam questions and answers Graded A+ Vectors M and N are parallel to the y-axis. Let a = | M + N | and b = |M| + |N.A student claims that is possible that ab. Which of the following indicates whether the claim is correct and provides a valid justification? - ☑ ☑ B) The claim is correct, because the vectors M and N could be in opposite directions. A person throws a marble straight up into the air, releasing it a short height above the ground and catching it at that same height. If air resistance is negligible, which of the following graphs of position y versus time t is correct for the motion of the marble as it goes up and then comes down? - ☑ ☑ B) In scenarios A, B, and C, shown in the figure, blocks with the masses indicated are attached to identical vertical springs. The block in each scenario is slowly lowered until it reaches equilibrium. Which of the following correctly ranks the distances Ax_a, Ax_b, and Ax_c that each block is lowered.
