An acceleration of +3.5 m/s² results when two forces act on an object. The first
force is 100 N to the right and the second force is 40 N to the right. (A) What is
the net force on the object? (B) What is the object's mass?

Answer:

Explanation:

Since the forces oppose each other (direction), the smaller is subtracted from the larger. The net force is

Fn = 100 - 40 = 60

Part B

Fn = m * a

a = 3.5 m/s^2

Fn = 60

60 =  m * a

60 = m * 3.5           Divide by 3.5

60/3.5 = m

m = 17.143
