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?
