Question

wo object of mass 100g and 200g are moving along the same lines and direction with velocity of 2ms¹ and 1ms¹ respectively they collide and after the collision the first object move at a velocity of 1.67ms¹ determine. the velocity of the second object.​

Answer 1

Answer:1.2m/s

Explanation:

As no external forces are acting conservation of momentam

M1U1+M2U2=M1V1+M2V2

0.1*2+0.2*1=0.1*1.6+0.2*V

V=1.2m/s

Note every value is in SI UNIT
