# can I get help explanations on these questions ATTACHMENT PREVIEW Download attachment Screenshot 2019-10-02 17.26.41.png A runner travels 2 km north, then 1 km west, then 1 km north, then 3 km east. The run took 45 minutes. (a) What was the total path length of the run (in m)? (b) What was the average speed of the run (in m/s)? (c) At the end of the run, how far was the runner from the beginning (in m)? During a 5-km race, a runner averaged 13 km per hour. What was her final time (in min)? If an object has a horizontal velocity of 50 m/s and horizontal acceleration is zero, what would be the horizontal velocity after 4 s (in m/s)? During a 400-m race, a runner crosses the 100 m mark with a velocity of 12 m/s. What would be her final position if she maintained her velocity for another 10 seconds (in m)? A soccer ball is rolling with a constant acceleration of -1.5 m/s2. At ti = 0 s, the ball has an instantaneous velocity of 14 m/s. After 3s of rolling, what would be the velocity of the ball (in m/s)?
