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 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?
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?
This figure (|a| = 14.5 m/s2) represents the total acceleration of a particle moving clockwise in a circle of radius r = 1.70 m at a certain instant of time. (a) For that instant, find the radial acceleration of the particle. m/s2 (toward the center) (b) For that instant, find the speed of the particle. m/s (c) For that instant, find its tangential acceleration. m/s2 (in the direction of the motion)

A train is moving along a straight track with an initial velocity of 8 m/s when it is subjected to a deceleration of a-1.6/v m/s2, where v is in m/s. 2. How far does the train travel before it stops? How much time does it take to stop? a. b.
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?
.4j A particle is moving with a velocity of U 7.4 The particle's acceleration is 0.18i-0.9j. +3 S At this instant the particle is moving along part of a curved path which can be estimated as a circle of radius R. This curving is provided by the component of acceleration perpendicular to the motion of the particle. What is the magnitude of the component of acceleration perpendicular to velocity? Answer in s2 Answer:
A particle is moving along a straight path such that the acceleration a = (3v2-2) m/s2, where v is in m/s. If v = 15 m/s when s = 0 and t = 0, please determine the particle’s position, velocity, and acceleration as functions of time.
