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?
A cyclist sprints at the end of a race to clinch a victory. She has an initial velocity of 11.3 m/s and accelerates at a rate of 0.610 m/s for 7.85 s. (a) What is her final velocity? (Enter the magnitude in m/s.) 16.089 m/s (b) The cyclist continues at this velocity to the finish line. If she is 300 m from the finish line when she starts to accelerate, how much time did she save (in s)? (c) The...
A long-distance runner has an average speed of 2 m/s during a race. How far does the runner travel in 25 min?
2. If the total acceleration of a particle moving in a circle is 12 m/s? when at an angle 60 east of the radius, what is the speed of the particle at this moment? 13. When a runner achieved a velocity of 15 m/s, she decelerates at a constant rate of 1.5 m/s2. How long does it takes her to stop and how far does she travel?
A runner moving with an initial velocity of 15.4 m/s slows down at a constant rate of -2.9 m/s2 over a period of 2 seconds. (a) What is her velocity at the end of this time? (b) What distance does she travel during this process?
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,...
Starting from rest, a runner at a track meet reaches a speed of 8.7 m/s in 1.9 s. How far does she run during this time, assuming her acceleration is uniform? Submit Answer Practice Another Version
Show All work step by step. Near the end of a marathon race, the first two runners are separated by a distance of 75.0 m. The front runner has a velocity of 3.25 m/s, and the second runner has a velocity of 4.75 m/s. What is the magnitude of the velocity of the second runner relative to the first? velocity of the second runner relative to the first: m/s If the front runner is 215 m from the finish line,...
