• The gravitational force that Earth exerts on the mood
equals 2.03x1020N. The moon’s mass equals
7.35x1022kg. What is the acceleration of the moon due
to Earth’s gravitational pull.
• 0.0027619= 2.76x10-3m/s2
• Assume that a catcher in a professional baseball game
exerts a foce of -65.0N to stop the ball. If the baseball
has a mass of 0.145kg, what is it’s acceleration as it is
being caught?
• -448.275862=-448m/s2
