Triceratops A set of fossilized triceratops footprints
Chapter 11, Problem 27P(choose chapter or problem)
A set of fossilized triceratops footprints discovered in Texas show that the front and rear feet were 3.2 m apart, as shown in Figure 11–27. The rear footprints were observed to be twice as deep as the front footprints. Assuming that the rear feet pressed down on the ground with twice the force exerted by the front feet, find the horizontal distance from the rear feet to the triceratops’s center of mass.

QUESTION:
A set of fossilized triceratops footprints discovered in Texas show that the front and rear feet were 3.2 m apart, as shown in Figure 11–27. The rear footprints were observed to be twice as deep as the front footprints. Assuming that the rear feet pressed down on the ground with twice the force exerted by the front feet, find the horizontal distance from the rear feet to the triceratops’s center of mass.
ANSWER:
Step 1 of 3
The footprints of a fossilized triceratops show that the rear feet pressed the ground two times greater than that of the front feet. The distance between the front and the rear feet is 3.2 m. We are going to find the horizontal distance from the rear feet to the center of mass of the triceratops.
