Question

Two objects of masses 100 g and 200 g are moving along the same line and

direction with velocities of 2 m/s and 1 m/s, respectively. They collide and after

the collision, the first object moves at a velocity of 1.67 m/s. Determine the

velocity of the second object.​

Answer 1

Answer:

Mass and velocity before collision is given

m1=100g

m2=200g

u1=2m/s

u2=1m/s

v1=1.67m/s

Let v2=v

m1u1+m2u2=m1v1+m2v2

{(100x2) +(200x1)}={(100x1.67) +(200xv2)

(200+200) =(167+200v2)

200v2=400-167

v2=233/200

v2=1.165m/s
