Agirl is her brother slide their dog m = 25kg along an icy frictionless sidewalk. the boy is pulling a rope t = 10n tied to the dogs collar and the girl is pushing with 7n of force. what is the net force on the dog and it's acceleration?

0.68 m/s²

Explanation:

Given:

Mass of the dog,  m = 25 kg

Tension in the rope = 10 N

Force applied by the girl on the dog = 7 N

Now,

since the boy is pulling the dog and the girl is pushing the dog

Thus,

The net force on the dog = 10 N + 7 N = 17 N

also,

Net force on the dog = Mass × Acceleration

thus,

25 kg × Acceleration = 17 N

or

Acceleration =

or

Acceleration = 0.68 m/s²

most of them using statistics and defining how things are being measured

e) none of the above answers are correct
