Engineering Mechanics Two balls of equal mass and of perfectly elastic material are lying on the floor. One of the balls with velocity ‘v’ is made to strike the second ball. Both the balls after impact will move with a velocity v/8 v/4 v v/2 v/8 v/4 v v/2 ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics If u₁ and u₂ are the velocities of two moving bodies in the same direction before impact and v₁ and v₂ are their velocities after impact, then coefficient of restitution is given by (u₂ + u₁)/(v₂ + v₁) (v₂ - v₁)/(u₁ - u₂) (u₁ - u₂)/(v₁ - v₂) (v₁ - v₂)/(u₁ - u₂) (u₂ + u₁)/(v₂ + v₁) (v₂ - v₁)/(u₁ - u₂) (u₁ - u₂)/(v₁ - v₂) (v₁ - v₂)/(u₁ - u₂) ANSWER DOWNLOAD EXAMIANS APP
