Question

Two identical objects, A and B, of mass M =

1 move along a horizontal air track. Object
B initially moves to the right with speed v =
1. Object A initially moves to the right
with speed y = 3, so that it collides with
object B. There is no friction.
a. Determine the total momentum of the
two objects (add their momentums
together

Answer 1

Step-by-step explanation:

p=mv

total momentum=m1v1+m2v2

=(1)(3)+(1)(1)

=4kgms^-1
