Calculating the magnitude of applied force:
- Initial velocity (u) = 3 m/s
- Final velocity (v) = 7 m/s
- Time taken (t) = 2 seconds
- Mass of the object (m) = 5 kg
Using the formula:
v = u + at
7 = 3 + a(2)
a = (7-3)/2
a = 2 m/s^2
Now, using the formula:
F = ma
F = 5 * 2
F = 10 N
Therefore, the magnitude of the applied force is 10 N.

Calculating final velocity with a duration of 5 seconds:
- Time taken (t) = 5 seconds
Using the formula:
v = u + at
v = 3 + 2(5)
v = 3 + 10
v = 13 m/s
Therefore, if the force is applied for a duration of 5 seconds, the final velocity of the object will be 13 m/s.
