Question
Remember that when dealing with collisions in 2-dimensions, momentum is conserved in each dimension. Two pucks are sliding on a frictionless tabletop. Block A (mass 3.46 kg) is moving to the East (+x direction) at 2.20 m/s. Block B (mass 4.15 kg) is moving to the North (+y direction) at 2.64 m/s. Assume the system to be both Block A and Block B. (Note: It could be useful to make a drawing of the situation.) What is the x-component of the total momentum of the system before the collision? What is the y-component of the total momentum of the system before the collision? What is the x-component of the total momentum of the system after the collision? What is the y-component of the total momentum of the system after the collision?Explanation / Answer
a)x-component =3.46*2.2
=7.612 kgm/s
b)y-component=4.15*2.64
=10.956 kgm/s
c)total momentum=7.612 i+10.956 j
d)x-component =3.46*2.2
=7.612 kgm/s
e)y-component=4.15*2.64
=10.956 kgm/s
