Average force applied by the call on the glove = 780 N
Explanation:
mass of baseball=0.140 kg
initial velocity = Vi= 35 m/s
Final velocity=Vf= 0
distance traveled=11 cm= 0.11 m
using the kinematic equation Vf²= Vi²+ 2 a d
where a = acceleration
0²= 35²+ 2 a (0.11)
a=-5568.2 m/s²
Now force is given by F= ma
F= 0.140 (5568.2)
F=-780 N
The negative sign signifies that the force acts in the opposite direction.
so the average force= 780 N
Answer: A, B, and D,
C is incorrect because continental drift takes several centuries to move the tectonic plates witch is not an immediate impact leaving you with A,B, and D.
The dinosaurs first appeared in the Mesozoic and the first mass extinction occurred during the Paleozoic. Moreover, humans first appeared in the Cenozoic.
<h3>The geological eras and biological events</h3>
The dinosaurs emerged during the Triassic Period of the Mesozoic Era, approximately 220-225 million years ago.
The first mass extinction occurred in the Ordovician Period (the second period of the Paleozoic Era).
The Cenozoic is the current geological Era that encompasses the last 60 million years.
