Questions
A lighter body collides head-on and elastically with heavier body at rest then after collision
a
Lighter body comes to rest, then heavier body begins to move with initial velocity of lighter body
b
The velocity of lighter sphere is reversed and the final velocity of heavier sphere approximately remains zero
c
Both lighter and heavier bodies exchange their velocities
d
Both lighter and heavier bodies come to rest
detailed solution
Correct option is B
mv1+Mv2=mu1+M×0……(1)v2−v1u1−u2=e=1….(2)∴v1=m−MM+mu1 and v2=2mM+m×u1For M>>m, v1 is negative and v2 =0Talk to our academic expert!
