Question

Two object of mass 100 gram and 200 gram on moving along the same line and direction with velocities of 2 metre per second and 1 m per second respectively they colloid and after collision the first object moves at the velocity of 1.67 metre per second determine the velocity of the second object

Answer 1

using conservation of momentum, if moving in same direction as previously..
100/1000kg ×2 + 200/1000 ×1 = 100/1000 ×1.67 + 200/1000 ×x
0.2+0.2=0.167+0.2x
0.4=0.167+0.2x
0.2x=0.233
x=0.233/0.2
x=233/200
x=1.165
