Answer #1

velocity of mA

vA = ( mA - mB) uA / ( mA + mB) + 2 mB uB / ( mA +. B)

vA = ( - m) v1 / 3m - 2* 2 m * v2 / ( 3m)

vA = - v1/3 - 4/3 v2

=====

velocity of

VB = (m2 - m1) V2 / ( m1 +m2) + 2 m1v1 (m1 + m 2)

Vb = - V2 / 3 + 2 v1/3

    Introduction: In this lab you will investigate the conservation of linear momentum: momentum before an event equals momentum after an event if there is an absence of a non-conservative forces such as friction. The event is this case is a collision between two air track gliders. Two types of collisions will be studied. One is an elastic collision which will not be studied in this lab. after the collision. The second is an inelastic collision where after two objects collide,...
