Question

An object accelerates 12.0 m/s2 when a force of 6.0 Newton's is applied to it .What is the mass of the object?

72 kg
6kg
2kg
0.5kg

Answer 1

Step-by-step explanation:

This is a direct application of Newton's 2nd Law:

F = ma, where F is the force applied to an object, m is the mass of the object, and a is the acceleration of the object when this force is applied. Note: this is NOT the same as the acceleration due to gravity which is constant at -9.8 m/s/s or -32 ft/s/s. Filling in:

6.0 = m(12.0) so

m = .5 kg
