He then goes 2 more laps in 3 minutes and 30 seconds before stopping at the point on the track where he began. What was his average velocity? 2. What was his displacement? 3. A basketball player dribbles down the court. At one point her velocity was 2.7 m/s, however, 0.4 seconds later, her velocity was 3.9 m/s. What was her acceleration during this time? 4. During a free kick (the ball is not moving previous to being struck) a soccer ball is kicked upward at a 40 degree angle (relative to the ground) with an initial velocity of 30 m/s. The players foot makes contact with the ball for only .23 seconds.What is the average acceleration the ball experiences while in contact with the foot? 5. Ignoring the effects of air resistance, what is the maximum height that the ball will reach?...
