Problem 20PE

Olympic-class sprinter starts a race with an acceleration of 4.50 m/s2 . (a) What is her speed 2.40 s later? (b) Sketch a graph of her position vs. time for this period.

Step-by-Step Solution:

Step-by-step solution Step 1 of 5 (a) Apply the kinematics equation, Here v is the final velocity, u is the initial velocity, a is the acceleration and t is the time interval during which a body is under acceleration. Step 2 of 5 Substitute for , for and for t. The final velocity of the sprinter is . Comment Step 3 of 5 (b) Use the kinematics equation, Here is the distance. Comment
