Answer:
B. 1520 N
Explanation:
The weight of each object can be calculated by using the formula:
[tex]W=mg[/tex]
where m is the mass of the object and g the acceleration due to gravity.
- The mass of the cow is m = 410 kg, so its weight is
[tex]W=mg=(410 kg)(9.8 m/s^2)=4018 N[/tex]
- The mass of the car is m = 565 kg, so its weight is
[tex]W=mg=(565 kg)(9.8 m/s^2)=5537 N[/tex]
So, the difference in weight is
[tex]\Delta W = 5537 N - 4018 N = 1519 N[/tex]
And the closest answer is
B. 1520 N
