A mass m moving horizontally with velocity v collides

Asked by admin @ 17/08/2021 in Physics viewed by 312 People

A mass m moving horizontally along x axis with velocity v collides and sticks to a mass of 3m moving vertically upwards with its velocity 2v. The final velocity of combination is

Answered by admin @ 17/08/2021

Mass = m
velocity = v
second mass= 3m
second velocity = 2v

final velocity = massxvelocity + 2nd mass x 2nd velocity/ sum of masses

=mvi + 3m₂vj/m + 3m
=v/4 i + 3v/2 j
