Chapter 15, Problem 2IP
A cyclist is riding at a speed of 14 km/hr into a 16 km/hr headwind. What is the wind velocity relative to the cyclist? What is the cyclist’s velocity with respect to the wind? (Answer: 30 km/hr in the direction of the wind; 30 km/hr in the direction of the cyclist)

Based on the acceleration in the above ball rolling down an inclined plane (with vo = 0 meters per second), how far would it have traveled along the inclined plane in the first six seconds of rolling?
9 meters
16 meters
25 meters
36 meters
49 meters
When Galileo Galilei pushed a ball down an inclined plane, it had an initial velocity (vo) of 4.0 meters per second (time = 0 seconds) and a final velocity (vf) of 10.0 meters per second (time = 2 seconds). How far did the ball travel along the inclined plane in these 2 seconds?
14 meters
20 meters
28 meters
40 meters
84 meters
The “mean-speed theorem” for finding average velocity under constant acceleration, proposed by the Oxford Calculators, and demonstrated geometrically by Nicole Oresme, is expressed algebraically as:
density = weight/volume
(m1)(v1) = (m2)(v2)
(vm) = 1/2 (v0 + vf)
s = (v0)(t) + 1/2 (a)(t2)
velocity = distance/time
