[1 point, 10 tries] An athlete swims the length of a 47.5 m pool in 19.4 s and makes the return trip to the starting position in 25.9 s. Determine her average velocity in the Frst half of the swim. Correct, computer gets: 2.45e+00 m/s 2 . [1 point, 10 tries] Determine her average velocity in the second half of the swim. Correct, computer gets: -1.83e+00 m/s 3 . [1 point, 10 tries] Determine her average velocity in the round trip. Answer: Not yet correct, tries 3/10 4 . [1 point, 10 tries] A tennis ball with a velocity of 11.8 m/s is thrown perpendicularly at a wall. After striking the wall, the ball rebounds in the opposite direction with a speed of 7.41 m/s. If the ball is in contact with the wall for 0.0138 s, what is the average acceleration of the ball while it is in contact with the wall? Correct, computer gets: -1.39e+03 m/s^2
