1. A car has an initial velocity of 25 m/s to the right and an acceleration of zero. Determine how far it
will travel in 3.0 seconds. Determine the final velocity of the car.
a. Draw a diagram
b. Find the givens
c. Describe y
The original review did not provide the initial velocity for problem 3. So youll notice in the solution the
arguments for using the 25 m/s in x and 14.7 m/s in y. If you use the daredevils calculated speed you get 29
m/s cos 30o = 25 m/s in the x and 29 m
