One Dimensional Collisions: Analyzing Impulse and Average Forces

In summary, a 2.50kg ball is thrown upward with an initial velocity of 19.6m/s. After it hits the thrower's hand, it comes to rest in 0.20s. To find the impulse exerted on the ball, we need to calculate the change in momentum before and after the collision. The average net force on the ball can be found by dividing the change in momentum by the time taken for the change. Additionally, the average force exerted by the hand on the ball can be calculated using the same equation.

Homework Statement


a ball of mass 2.50kg is thrown upward. it leaves the hand w/ an upward velocity of 19.6m/s.
(on the way down now )after the ball hits the throwers hand it comes to rest in .20s
a. What is the impulse exerted on the ball?
b. What is the average net force on the ball during this time?
c. What is the average force exerted by the hand on the ball?

Homework Equations

Your Relevant Equation gives you a big hint. Looks like you want to find the change in momentum as the ball is caught.

You must make some attempt or at least show what you know and where your confusion lies or your question will be marked for deletion!
 
  • #3
for the first question you have to just find the momentum before collision and momentum after collision with the hand and subtract.
For the second,Average force=(Change in momentum /time taken for the change)
 

Related to One Dimensional Collisions: Analyzing Impulse and Average Forces

1. What is a one dimensional collision?

A one dimensional collision is a type of collision that occurs between two objects moving in a straight line along the same path, with no movement in any other direction. This type of collision is often studied in physics and can involve objects of any size, from subatomic particles to planets.

2. What is the law of conservation of momentum in one dimensional collisions?

The law of conservation of momentum states that the total momentum of a closed system remains constant before and after a collision. In one dimensional collisions, this means that the total momentum of the objects before the collision must be equal to the total momentum after the collision.

3. How is kinetic energy conserved in one dimensional collisions?

In one dimensional collisions, kinetic energy is conserved when there is no external force acting on the system. This means that the total kinetic energy of the objects before the collision must be equal to the total kinetic energy after the collision. However, if there is an external force, such as friction, some kinetic energy may be lost in the form of heat or sound.

4. What is an elastic collision?

An elastic collision is a type of collision in which the total kinetic energy of the system is conserved. This means that the objects involved in the collision bounce off each other without any loss of energy. In one dimensional collisions, elastic collisions occur when there is no external force present and the objects involved are perfectly elastic, meaning they can deform and return to their original shape without any loss of energy.

5. How do you calculate the velocities of objects after a one dimensional collision?

To calculate the velocities of objects after a one dimensional collision, you can use the principle of conservation of momentum and the equations for conservation of kinetic energy. First, you must calculate the initial and final momentums of the objects, and then set them equal to each other to solve for the final velocities. If the collision is elastic, you can also use the equation for conservation of kinetic energy to calculate the final velocities.
