Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 1) i.e. 4 Ns
CONCEPT:
- Momentum: Momentum is the impact due to a moving object of mass m and velocity v. The momentum (p) of an object is expressed as:
⇒ p = mv
- Impulse: The change in momentum of an object when the object is acted upon by a force for a certain amount of time is called impulse.
The Impulse is expressed mathematically as:
⇒ Δp = FΔt
Where Δp is the change in momentum, F is force, and Δt is the time taken.
EXPLANATION:
- The area under the net force vs time graph represents the change in momentum i.e. impulse.
The change in linear momentum between 0 s 8 s = \(\frac{1}{2} \times 8\:s \times 1\:N = 4 \:Ns\)
