Question 3

An object of mass 2.0 kg is moving in a straight line at a velocity of 8.0 m s^-1. It collides with an identical object also travelling at 8.0 m s^-1 in a straight line. Their initial velocities are perpendicular. The two objects stick together. What is the magnitude in $s−1\text{m s}^{-1}$ of the new combined velocity?

A

$4.0$

B

$5.7$
