1) An 18-year-old runner can complete a 10.0 km course with an average speed of 4.52 m/s. A 50-year-old runner can cover the same distance with an average speed of 4.07 m/s. How much later (in seconds) should the younger runner start in order to finish the the course at the same time as the older runner? s 2) A sprinter explodes out of the starting block with an acceleration of +3.8 m/s2, which she sustains for 1.4 s. Then,...
2 At the end of a race a runner decelerates from a velocity of 7.00 m/s at a rate of 0.500 m/s. (a) How far does she travel in the next 16.0 s? (b) What is her final velocity? X m/s Enter a number Additional Materials Reading Submit Answer Save Progress
At the end of a race a runner decelerates from a velocity of 7.00 m/s at a rate of 0.300 m/s2. (a) How far does she travel in the next 14.0 s? m (b) What is her final velocity? m/s
At the end of a race a runner decelerates from a velocity of 8.70 m/s at a rate of 2.40 m/s2. How far in meters does she travel in the next 4.10 s? (Assume the deceleration of 2.40 m/s2 is constant over the full 4.10 s.) m What is her final velocity in m/s? Evaluate the result. Does it make sense?
At the end of a race, a runner decelerates to a stop from a velocity of 8 m/s at a rate of 1.88 m/s2. How far does she travel in 8.6 s from when she begins decelerating?
An 18-year-old runner can complete a 10.0-km course with an average speed of 4.40 m/s. A 50-year-old runner can cover the same distance with an average speed of 3.91 m/s. How much later (in seconds) should the younger runner start in order to finish the course at the same time as the older runner?
An 18-year-old runner can complete a 10.0 km course with an average speed of 4.33 m/s. A 50-year-old runner can cover the same distance with an average speed of 4.18 m/s. How much later (in seconds) should the younger runner start in order to finish the course at the same time as the older runner?
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 isn’t 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...
How far does the runner whose velocity–time graph is shown in the figure travel in 16 s? The figure's vertical scaling is set by vs = 8.00 m/s. 2 4 0 (s/u)
