Answer:
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
