Questions
A steel ball of mass 1 kg, moving with a velocity of 2 m/s collides head-on and elastically with an identical steel ball. What is impulse acting on the second ball during the course of collision?
detailed solution
Correct option is D
As a result of head-on elastic collision between the identical spheres, the first spheres will stop and the second one will start moving with velocity of 2 m/s.∴ Impulse=1×2 Kg−m/s=2 Kg−m/sTalk to our academic expert!
