Answer:
17 N
Step-by-step explanation:
Weight is a force. The equation to calculate a force is:
![F=ma](https://img.qammunity.org/2021/formulas/physics/college/kxqi3lxi3fjfv761qhdu0s1p00agxd9vve.png)
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](https://img.qammunity.org/2021/formulas/physics/high-school/ktwp1jd67cyaj7ft7wg18fviyh5rpkk8ro.png)
Forces are measured in Newtons (N) so the answer is 17 N.
