Asimple pendulum is displaced to the left of its equilibrium position and is released from rest. set the origin of the coordinate system at the equilibrium position of the pendulum, and let counterclockwise be the positive angular direction. assume air resistance is so small that it can be ignoredpart a:
beginning the instant the pendulum is released, select the graph that best matches the angular position vs. time graph for the pendulum.
part b:
beginning the instant the object is released; select the graph that best matches the velocity vs. time graph for the object.
part c:
beginning the instant the object is released; select the graph that best matches the acceleration vs. time graph for the object.
guys! im so lost on this : /

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
