An athlete is training on a 100 m long linear track. His motion is described by the graph of his position vs. time, below. For each segment of the graph, find the magnitude and direction of the athlete's velocity.   magnitude vA _______ m/s   direction vA(Pick from the following choices) - Positive x - Negative x - The magnitude is zero   magnitude vB _______ m/s   direction vB(Pick from the following choices) - Positive x - Negative x - The magnitude is zero   magnitude vC _______ m/s   direction vC(Pick from the following choices) - Positive x - Negative x - The magnitude is zero magnitude vD _______ m/s   direction vD(Pick from the following choices) - Positive x - Negative x - The magnitude is zero

Two kids are racing towards a toy somewhere between them. Albert has 3.90 times further to run than Betty. Albert is to the West of the toy and Betty is to the East of the toy. Albert runs at a constant speed of 1.60 m/s. It takes him 2.90 s to reach the toy.How far did Albert run to reach the toy?

A group of students in a science class monitored the movement of a cat walking along with a straight line and recorded the cat's position in five-second intervals.The results are summarized it in the table below.  time and position time(s) position (cm) 0 49.0 5 38.0 10 43.0 15 40.0 20 60.0   A. What is the displacement of the cat between t = 5.00 s and t = 20.0 s?   B. What is the average velocity of the cat between t = 5.00 s and t = 20.0 s?   C.What is the distance the cat traveled between t = 5.00 s and t = 20.0 s?

One of the fastest known animals is the Indian spine-tailed swift. A swift flies 2.80 km due north in a time of 32.8 s. a. What is its average velocity due north in meters per second? Enter a positive value if the average velocity is due north and enter a negative value if it is due south. answer in m/s b. What is its average velocity due north in miles per hour? Enter a positive value if the average velocity is due north and enter a negative value if it is due south. anser in mi/h

A vehicle is moving at +36.0 m/s when the driver sees a stop sign. In 2.60 seconds, the vehicle comes to a stop. 1) Find the vehicle’s acceleration (magnitude and direction). 2) Find the vehicle’s displacement (magnitude and direction).
