Physics question.

Option C. 6.7 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) of hockey puck = 0.67 kg

Time (t) = 7 s

Velocity (v) = 3.1 m/s

Acceleration due to gravity (g) = 10 m/s²

Weight (W) of hockey puck =?

The weight of an object is simply defined as the gravitational pull on an object. Mathematically, it is expressed as:

Weight = mass × acceleration due to gravity

W = m × g

With the above formula, we can obtain the weight of the hockey puck as follow:

Mass (m) of hockey puck = 0.67 kg

Acceleration due to gravity (g) = 10 m/s²

Weight (W) of hockey puck =?

W = m × g

W = 0.67 × 10

W = 6.7 N

Thus, the weight of the hockey puck is 6.7 N
