Question

4. Two runners in a 100 m race start from the same place. Runner A starts as soon as the starting gun is fired and runs at a constant speed of 8.00 m/s. Runner B isnt really paying attention and starts running 2.0 s later and runs at a constant speed of 9.3 m/s. a. Draw a position vs time graph for each runner. b. Who wins the race? c. At the instant the winner crosses the finish line, how far is the winner ahead of the other runner? d. If the runners decide they want to cross the finish line together, and Runner A again begins the instant the starting gun is fired, how many seconds should Runner B delay in order to catch Runner A exactly at the finish line?

    Races in athletics are started by the sound of a starting gun, traditionally located to one side of the first lane. But are runners disadvantaged if they are further away from the person holding the starting gun? Task Using algebra, investigate whether the distance from the starting gun will impact on a runner’s ability to win a race. Explore which runners would be most disadvantaged if the race was won by 0.1 seconds or 0.01 seconds. Useful information  Runners...

    Runner Rendezvous. Two runners start simultaneously at opposite ends of a straight 200 m track and run towards each other. Runner A runs at a steady 9.00 m/s, while Runner B runs at a constant 5.00 m/s. a) Draw a diagram of this situation. Include a coordinate system in your diagram, and label the initial positions and velocities of both runners. Also estimate where the runners would meet and label it as x. b) Write equations for the position of...

    In a quarter-mile drag race, two cars start simultaneously from rest, and each accelerates at a constant rate until it either reaches its maximum speed or crosses the finish line. Car A has an acceleration of 11.6 m/s2 and a maximum speed of 108 m/s. Car B has an acceleration of 11.7 m/s2 and a maximum speed of 91.0 m/s. Which car wins the race, and by how many seconds?

The second runner waits 3 seconds and then throws a rock at his opponent's head. If the head and the rock are at the same level form the ground, what must the initial magnitude of the velocity be if the rock is to hit the head just at the 109 yard tape? Give the...

    During a track event two runners, Bob, and Jim, round the last turn and head into the final stretch with Bob a distance d in front of Jim. They are both running with the same velocity v 0 . When the finish line is a distance s away from Jim, Jim accelerates at a constant a J until he catches up to Bob and passes him. Jim then continues at a constant speed until he reaches the finish line. a)...
