Question

A large fish with a mass of 3.65kg moving with an initial velocity of 5.0 m/s grabs a smaller fish with a mass of 1.30 kg. If the smaller fish was moving in the same direction as the larger fish at a speed of 2.5 m/s before he was eaten, what is the velocity of the two fish after impact?

Answer 1

Step-by-step explanation:

m1= 3.65kg

v1= 5 m/s

m2= 1.3 kg

v2= 2.5 m/s

V=?

m1*v1 + m2*v2 = (m1+m2) * V

V= (m1*v1 + m2*v2) / (m1+m2)

V= 4.34 m/s
