Question Number 16155 by Tinkutara last updated on 18/Jun/17

A body of mass m is projected with a

speed v making an angle θ with the

vertical . What is the change in

momentum of the body along the Y -

axis; between the starting point and the

highest point of its path ?

p a t h = 0

c h a n g e i n y - c o m p o n e n t

o f m o m e n t u m = - m v \cos θ .
