A Rugby player runs from his own try line (goal line) to his opponents' try line (goal line), and then runs back to his own 25 m line, all in a time of 18.5 s. His average speed was 6.8 m-s1, and his average velocity was 4.1 m-s 1. NOTE: Rugby try lines (goal lines) are 100 m apart. All of the field lines can be considered defined values.

- Problem 1: Near the end of a foot race, the front two runners are separated by a distance of 45 m. The race leader has a velocity of 3.5 m/s and the second runner has a velocity of 4.2 m/s. a) What is the velocity of the second runner relative to the first? b) If the frontrunner is 250 m from the finish line, who wins the race? c) How far ahead of the second runner does the eventual winner finish?Please asapNear the end of a marathon race, the first two runners are separated by a distance of 45.6 m. The front runner has a velocity of 3.2 m/s, and the second a velocity of 4.95 m/s. a) What is the velocity of the second runner relative to the first, in meters per second? b) How many seconds earlier will the second runner reach the finish line if the front runner is 250 m from the finish line in seconds? c) What distance ahead, in meters, will the second runner be when she crosses the finish line? please answer all parts
- You throw an object up with an initial velocity of voy=13 m/s from a height of y=25 m. Part a) How long, in seconds, does it take for the object to reach the ground? Part b) What is the object's final velocity, in meters per second, as it impacts the ground? Part c) Find the time, in seconds, if you instead threw the object down with the same velocity, voy?Two cars are driving, car 1 has initial position -3500m, initial velocity -55m/s and acceleration +1.25m/s2, car 2 has initial position +4100m, initial velocity -35 m/s and acceleration +0.75m/s2; a) How much time until they collide? b) What is the x location where they collide, and the final velocity of each car?A particle moves in such a way that a = 2t + 2 m/s/s, where t is in seconds.

- Current Attempt in Progress In reaching her destination, a backpacker walks with an average velocity of 1.41 m/s, due west. This average velocity results, because she hikes for 6.94 km with an average velocity of 2.42 m/s due west, turns around, and hikes with an average velocity of 0.638 m/s due east. How far east did she walk (in kilometers)? VW 71 Number i West Units dw VE East dEYou decide to relax & play some basketball (m = 413g). You throw the ball from an initial height of 1.13m (represented by hA on the diagram). When it hits the net (which is 2.20m high), it has a speed of 7m/s. How fast was the ball going when it left your hand? hA = height of throw = 1.13m hB = height of net = 2.20m %3DA lion is napping in the shade as a zebra saunters by at steady 48.2 km/h. Feeling the desire for dinner the lion accelerates at 4.44m/s2 for 5.00 seconds. What velocity will the lion attain after 5.00 seconds? Graph the motion (velocity vs. time) of the lion and the deer for the entire scenario. Label the axis and any major points.
- I need part d and ePlease answer correctly. Thank you!!A ball is dropped from a height of 3 m and rebounds from the floor to a height of 2 m.a) What is the velocity of the ball just as it reaches the floor?b) What is the velocity just as it leaves the floor?c) If it is in contact with the floor for 0.02 s, what are the magnitude and direction of its average acceleration during the interval?
