Question

A dog has a mass of 60kg and an acceleration of 2m/s/s. What is the force of the dog?

1) 30N
2) 120N
3) 15N
4) 1200N

Answer 1

The force exerted by a 60 kg dog with an acceleration of 2 m/s² is 120 N, calculated using Newton's second law of motion (F = m × a).

Step-by-step explanation:

The force exerted by the dog can be determined using Newton's second law of motion, which states that force equals mass times acceleration (F = m × a). Given that the dog has a mass of 60 kg and an acceleration of 2 m/s², the force exerted by the dog is calculated as follows:

F = m × a
= 60 kg × 2 m/s²
= 120N

Therefore, the correct answer is 120N, which corresponds to option 2).
