Explanation: Please see the attachment below
Answer:
m1 = the mass of the blue sphere = 5.8 kg
m2 = the mass of the red sphere = 2.5 kg
v1 = initial velocity of the blue sphere before the collision = 4.1 m/s
v2 = initial velocity of the red sphere before the collision = 0 m/s
v'1 = final velocity of the blue sphere after the collision = 1.3 m/s
v'2 = final velocity of the red sphere after the collision = ?
using conservation of momentum
m1v1 + m2v2 = m1v'1 + m2v'2
(5.8) (4.1) + (2.5) (0) = (5.8) (1.3) + (2.5) (v'2)
23.78 = 7.54 + (2.5) (v'2)
-7.54 -7.54
16.24 = (2.5) v'2
--------- -----------
2.5 2.5
v'2 = 6.5
