Consider a runner moving in the positive direction with an initial velocity of 5.8 m/s slows down at a constant rate of -0.7 m/s2 over a period of 2 seconds. What is her velocity at the end of this time? ______ m/s
Consider a car moving in the positive direction with an initial velocity of 37 m/s slows down at a constant rate of -1.5 m/s2. What distance does the car cover in 10 seconds in meters?
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?

What was the net displacement during the 150...
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?
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,...
A car traveling at 20 m / s slows down at a rate of 0.50m / s2. Calculate: a) The distance the car traveled when it stopped. b) The time it takes to stop. c) The distance traveled by the car in the first three seconds after it begins to decelerate.
