Question

A particle of mass m is projected from the ground with initial linear momentum p (magnitude) such that to have maximum possible range. Its minimum kinetic energy will be


A
p22m
loader
B
p24m
loader
C
p2m
loader
D
p26m
loader

Solution

The correct option is B p24m
Range will be maximum when angle of projection is 45.
Let u be the initial velocity with which the particle is projected.
Initial linear momentum is given by
p=mu
pmin=mu cos 45=mu2=p2
Kmin=p2min2m=(p2)22m=p24m
