Question

A hammer has a mass of 1.7kg. How much does it weigh?

Answer 1

17 N

Step-by-step explanation:

Weight is a force. The equation to calculate a force is:

`F=ma`

where a is the acceleration of the object. On an object simply existing, the force of gravity adds an acceleration of 9.8m/s², or approximately 10m/s². So, to calculate the force of weight, we simply multiply the mass by 10 for that reason:

`F_w = 1.7(10) = 17N`

Forces are measured in Newtons (N) so the answer is 17 N.
