A 100-N force causes an object to
accelerate at 2 m/s/s. What is the
mass of the object?

.

Explanation:

By Newton's Second Law, the acceleration of an object is proportional to the net force on it. In particular, if the mass of the object is , then

.

Rewrite this equation to obtain:

.

In this case, the assumption is that the force is the only force that is acting on the object. Hence, the net force on the object would also be

Make sure that all values are in their standard units. Forces should be in Newtons (same as , and the acceleration of the object should be in meters-per-second-squared (). Apply the equation to find the mass of the object.
