Engineering Mechanics A lead ball with a certain velocity is made to strike a wall, it falls down, but rubber ball of same mass and with same velocity strikes the same wall, it rebounds. Select the correct reason from the following: The change in momentum suffered by rubber ball is less than the lead ball None of these Both the balls undergo an equal change in momentum The change in momentum suffered by rubber ball is more than the lead ball The change in momentum suffered by rubber ball is less than the lead ball None of these Both the balls undergo an equal change in momentum The change in momentum suffered by rubber ball is more than the lead ball 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 (v₂ - v₁)/(u₁ - u₂) (v₁ - v₂)/(u₁ - u₂) (u₂ + u₁)/(v₂ + v₁) (u₁ - u₂)/(v₁ - v₂) (v₂ - v₁)/(u₁ - u₂) (v₁ - v₂)/(u₁ - u₂) (u₂ + u₁)/(v₂ + v₁) (u₁ - u₂)/(v₁ - v₂) ANSWER DOWNLOAD EXAMIANS APP
