A booklet is a small book—with fewer pages and smaller dimensions than a “real” book, and usually a paper cover.
Answer:
the lever in which the fulcrum lies in middle is first
t
Impulse = change in momentum = F x dt
Where F is sufficiently large and dt is very small(tending to zero).
Therefore impulse = mass x final velocity - mass x initial velocity
= 975 x 3 - 975 x 0.5
= 2437.5 Kg-m/s.
Hence option C is correct.
