Question
The $15-\mathrm{lb}$ rod $A B$ is released from rest in the vertical position. If the coefficient or restitution between the floor and the cushion at $B$ is $e=0.7$, determine how high the end of the rod rebounds after impact with the floor.
Step 1
When the rod is released from the vertical position, it starts to rotate about point A. We can use conservation of energy to find the velocity of end B just before impact. The initial potential energy of the rod is converted into kinetic energy. Initial Show more…

The $15-1 b$ rod $A B$ is released from rest in the vertical position. If the coefficient or restitution between the floor and the cushion at $B$ is $e=0.7,$ determine how high the end of the rod rebounds after impact with the floor.
The 4 -lb rod $A B$ is hanging in the vertical position. A $2-1 b$ block, sliding on a smooth horizontal surface with a velocity of $12 \mathrm{ft} / \mathrm{s}$, strikes the rod at its end $B$. Determine the velocity of the block immediately after the collision. The coefficient of restitution between the block and the rod at $B$ is $e=0.8$
The coefficient of restitution between a ball and the floor is 0.60. If the ball is dropped from rest at a height of 6.6m from the floor, (a) what maximum height will the ball attain after the first bounce and (b) how much kinetic energy is lost during the impact if the mass of the ball is 0.9 kg?
