Question

Two billiard balls of mass 50 g moving in opposite
directions with speed of 16 ms collide and
rebound with the same speed. What is the impulse
imparted by each ball to the other?​

Answer 1

Answer:

Explanation:

Given,

Mass, m=50 gram=0.05 kg

Initial velocity, V  

initial

​  

=16ms  

−1

 

Final velocity, V  

final

​  

=−16 ms  

−1

 

Change in momentum is ΔP=m(V

)  

ΔP=0.05×(16−(−16))=1.6kgm/s

Impulse imparted to each ball due to collision is 1.6kgm/s .
