On an air track, a 400 g glider moving to the right at 2.00 m/s collides elastically with a 500 g glider moving in the opposite direction at 3.00 m/s
Find the velocity of first glider after the collision.
v= m/s to the left.
Find the velocity of second glider after the collision.
v= m/s to the right
