How long does it take the ball in problem 5 to travel 15 meters after being played? Neglect the gravitational effect, and suppose the ball travels along a straight line and assume a speed of 24 m/s.
A racecar driver steps on the gas, and his car travels 16 meters in 2 seconds, starting from rest. What is the average velocity in m/s and in km/h?
What is the average acceleration of the racecar in problem 7 in m/s2?
Refer to Figure 3.1 for numerical values needed to solve the following problems.
