Motion In A Plane

Question

A particle of mass is projected with the velocity v making an angle of 45^o with the horizontal.
When the particle lands on the level ground the magnitude of the change in its momentum will be

2 mv

$mv divided by square root of 2$
$square root of 2 mv$

zero

Solution

square root of 2 mv

The horizontal momentum does not change. The change in vertical momentum is

mv sin θ - (-mv sin θ )
=

2 space mv fraction numerator 1 over denominator square root of 2 end fraction space equals space square root of 2 space mv
