Question:
A Ping-Pong ball is acted upon by the Earth, air resistance, and a strong wind. Here are the positions of the ball at several times. Early time interval: At = 12.92 s, the position was <3.03, 2.77, -8.4> m. At = 12.98 s, the position was <3.14, 2.62, -8.610> m. Late time interval: At = 16.92 s, the position was <11.41, -1.32, -22.610> m. At = 16.98 s, the position was <11.64, -0.98, -22.820> m.
(c) In the time interval from = 12.92 s (the start of the early time interval) to = 16.92 s (the start of the late time interval), what was the average net force acting on the ball? Express your result as a vector.
