A pole-vaulter is nearly motionless as he clears the bar, set 4.2 mm above the ground. He then falls onto a thick pad. The top of the pad is 80 cmcm above the ground, and it compresses by 50 cmcm as he comes to rest.
Required:
What is his acceleration as he comes to rest on the pad?

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.
