Problem 1 (3.0 pts.). A hiker walks with an average speed of V = 2.5 m/s. (a) What distance in kilometers and in meters does the hiker travel in a time of t = 2 hours? (b) How much time did it take her to complete the Ist kilometer of her journey? Problem 2 (3.5 pts. ). A ball is thrown upward with an initial velocity of Vi = 12m/s. Use the approximate value of g = 10m /s2 for your calculations. (a) What is the velocity of the ball ti = 1.0 seconds after it is thrown? (b) What will be the location of the ball after to - 2.0 seconds compared to it initial position
