Homework Statement
A 0.1 kg rubber ball and a 0.1 kg clay ball are both thrown at the wall with the same initial velocity. the rubber ball bounces, the clay ball sticks. Which exerts a larger impulse on the wall?
Impulse of clay and rubber ball on the wall
In summary, the impulse of clay and rubber ball on the wall is the change in momentum that occurs during a collision. It affects the motion of the ball by causing a change in velocity, and is influenced by factors such as mass, velocity, stiffness, and impact duration. The elasticity of the ball and wall also plays a role in determining the impulse. It can be measured using a force sensor or by calculating the change in velocity using the principle of conservation of momentum.

is it the ball bouncing back? since the momentum of the clay ball after collision is 0

The impulse exerted on the wall by the rubber ball will be larger compared to the clay ball. This is because the change in momentum of an object is directly proportional to the impulse applied to it. Since both balls have the same initial velocity, the change in momentum for both will be the same. However, the rubber ball will experience a greater change in momentum due to its elastic nature, causing it to bounce off the wall with a higher velocity compared to the clay ball which sticks to the wall. This higher change in momentum results in a larger impulse exerted on the wall by the rubber ball.
1. What is the impulse of clay and rubber ball on the wall?
The impulse of clay and rubber ball on the wall refers to the change in momentum that occurs when the ball collides with the wall. It is a measure of the force and time of the impact, and is calculated by multiplying the average force exerted on the wall by the duration of the impact.
2. How does the impulse of clay and rubber ball on the wall affect their motion?
The impulse of clay and rubber ball on the wall affects their motion by causing a change in their velocity. This change in velocity is due to the force exerted on the ball by the wall during the collision, as well as the duration of the impact. The greater the impulse, the greater the change in velocity and the more significant the effect on the ball's motion.
3. What factors influence the impulse of clay and rubber ball on the wall?
The impulse of clay and rubber ball on the wall is influenced by several factors, including the mass and velocity of the ball, the stiffness of the wall, and the duration of the impact. A heavier and faster moving ball, a stiffer wall, and a longer impact duration will result in a larger impulse.
4. How does the elasticity of the ball and wall affect the impulse?
The elasticity of the ball and wall can have a significant impact on the impulse. If both the ball and wall are highly elastic, the impulse will be larger as the ball will bounce off the wall with more force. However, if either the ball or wall is not very elastic, the impulse will be smaller as more energy will be lost during the collision.
5. How is the impulse of clay and rubber ball on the wall measured?
The impulse of clay and rubber ball on the wall can be measured using a variety of methods. One common method is to use a force sensor to measure the average force exerted on the wall during the collision and then multiply it by the duration of the impact. The impulse can also be calculated using the initial and final velocities of the ball and applying the principle of conservation of momentum.
