Question

A coyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.20s later.

Answer 1

Find the x and y components of the coyote’s average acceleration during that time.

Answer 2

Let north be the y axis and east be the x axis.

starting velocity v1 = (8, 0)

second velocity v2 =(0, -8.80)

change in velocity vector = (0, -8.80) -(8, 0)

time needed for change = 4.20 s

acceleration vector = change in velocity vector / 4.20 s
