A resultant force of 4.0N acts on an object of mass 0.50 kg for 3.0 seconds. What is the change in velocity caused by this force? A= 4.0 m / s B= 6.0 m / s C= 12 m / s D= 24 m / s plz can someone explain

Units are ignored in calculation.
Answer:
D
Explanation:
- Acceleration = change in velocity / time taken in that change
- Force = mass * acceleration
Here,
= > 4 = 0.5 * acceleration
= > 4/0.5 = acceleration
= > 8 = change in velocity / time taken
= > 8 = change in velocity / 3
= > 8 * 3 = change in velocity
= > 24 = change in velocity
Correct option is 24 m/s.
