Given:
A 2.0 kilogram object is falling freely near earth's surface.
Determine the magnitude of the gravitational force that Earth exerts on the object.
Formula for force:
F = ma
m = mass
a = acceleration
Graviational acceleration = 9.8 m/s^2
Solution:
In order to determine the magnitude exerted by Earth, we simply substitute the given values of mass and acceleartion to the formula for foce.
F = ma
F = (2kg)(9.8m/s^2)
F = 19.6 kg . m/s^2
F = 19.6 N
Final answer:
F = 19.6 N
