Figures (a), (b), (c) and (d) show variation of force with time.

The impulse is highest in figure.

(1) Fig (c)

(2) Fig (b)

(3) Fig (a)

(4) Fig (d)

Show Answer

Answer: (2)

Solution:

Formula: Impulse

Impulse $=$ Area under $F=t$ curve

(a) $\frac{1}{2} \times 1 \times 0.5=\frac{1}{4}$ N.s

(b) $0.5 \times 2=1$ N.s (maximum)

(c) $\frac{1}{2} \times 1 \times 0.75=\frac{3}{8}$ N.s

(d) $\frac{1}{2} \times 2 \times 0.5=\frac{1}{2}$ N.s
