A constant force acts on an object of mass 6 kg for a duration of 5 seconds. It increases the object's velocity from 3 m/s to 8 m/s. Find the magnitude of the applied force.
Show answer & explanation
Correct answer: A
Explanation
Correct Answer:
Option 1: 6 N
Explanation:
To solve this problem, Newton's Second Law is applied:
Force = Mass × Acceleration
Change in velocity = 8 – 3 = 5 m/s
Time = 5 seconds
Acceleration = 5 / 5 = 1 m/s²
Now,
Force = 6 × 1 = 6 N
Therefore, the applied force is 6 Newtons.
