By Newton's second law, the net force exerted on the object makes it undergo an acceleration a such that
(2 kg) a = 5 N
so that it is accelerated a = 2.5 m/s^2.
Since the object starts with velocity 3 m/s, after 7 s its acceleration will make it speed up to
3 m/s + (2.5 m/s^2) (7 s) = 20.5 m/s
Answer:
<h2>Newton Second low say" the acceleration of a body id directly proportional to the force acting on the body and inversly proportional to tje mass of the body "</h2>
Explanation:
Newton's second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ... Newton's second law is one of the most important in all of physics.
<h3>I Hope my answer is Helpfull thanks</h3>
A
Because it is the only one that show an increase in both the temperature and rate or reaction
