If the impulse is 12 newton . seconds and the force is 5 newtons, how long did the force act?
1 answer:
2.4s
Explanation:
Given parameters:
Impulse = 12Ns
Force = 5N
Unknown:
Time taken for the force to act = ?
Solution:
Impulse is the change in momentum of a body when an external force acts on body for a period of time.
Impulse = force x time
Since the unknown in this problem is time, we make it the subject of the formula;
Time =
Inputting the parameters;
Time taken for force to act = = 2.4s
