The impulse of a force is deduced from Newton's second law as
A
F = ma
B
F = m( \(\frac{v - u}{t}\))
C
F = mg
D
F = mv - mu
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Force = mass x acceleration
But acceleration = \(\frac{v - u}{\text{t}}\)
F = m x (\(\frac{v - u}{\text{t}}\))
Ft = mv - mu.
