What would be the force on the body in Example 2.2 if its mass were 856 grams?


Assume that on the surface of the Earth, g = 9.81 m/s2 = 32.2 ft/s2 (i.e., each to three significant figures). Make sure you are reporting the solution to the proper number of significant figures.


Example 2.2

What is the force in newtons on a body of mass 102 g (0.102 kg) that is accelerated at 9.81 m/s2? Equation (2.4) is the principle we use:

 F = ma = 0.102 x 9.81 [kg][m/s2]= 1.00 [kg-m/s = 1.00 N

F = ma = 0.102 x 9.81 [kg][m/s2]= 1.00 [kg-m/s = 1.00 N
