Question 17 2 pts A and B can both walk at a speed 2.4 m/s and run at a speed 5.5 m/s. They start off together to go a distance 65 m. A walks for one half of the time it takes him to reach the distance, and runs for the remaining half the time. B, on the other hand, walks for half the distance, and runs for the remaining half the distance. Calculate how much sooner will A reach the distance as compared to B.
Question 11 2 pts A ball is projected vertically upward at time t 0.00 s, from the ground and experiences negligible air resistance. The ball rises, then falls and strikes the ground. The initial velocity of the ball is 17 m/s. The time when it is 6 m above the ground and moving downwards is (in seconds)11 and 17
