For example 32, considering equal mases, get the expressions for the velocities of bodies after the collision. |

Answer» SOLUTION :Put `m_(1)=m_(2)=m(say), ` in equations (x) & (xi) PUTTING `m_(1)m_(2)=m` in equation (10) `v_(1)=(m-m)/(m+m)u_(1)+(2m)/(m+m)u_(2)` `v_(1)=u_(2)` i.e., velocity of A after collision = velocity of B before collision From equation (11) `v_(2)=(2m u_(1))/(m+m)=((m-m)u_(2))/(m+m)` `v_(2)=u_(1)` i.e., velocity of B after collision = velocity of A before collision `implies` When two BODIES of equal masses undergo elastic collision in one dimension, their velocities are interchanged. |
