Question

the graph shows the relationship between the kinetic energy of a baseball in joules and the speed of the baseball in meters per second. based on the graph, approximately what is the kinetic energy, in joules, of a baseball traveling at a speed of 35 meters per second?
choose 1 answer:
a 50
b 70
c 90
d 110

Explanation:

Step1: Locate x = 35 on the x - axis

Find the position of 35 meters per second on the horizontal (x) axis of the graph.

Step2: Find the corresponding y - value

From the x - value of 35, move vertically until intersecting the graph. Then, move horizontally to the y - axis (kinetic energy in joules) to find the approximate value. Looking at the graph, when x = 35, the y - value (kinetic energy) is approximately 90 joules.

Answer:

C. 90
