    Impulse
In summary, the conversation is about a collision between a 5 kg ball and a 0.5 kg cube. The cube is traveling at a speed of 26m/s and collides with the motionless ball on the edge of a table. The total impulse given to the ball is 13 Newtons*sec, and the velocity of the ball immediately after the collision is unknown. The speed and direction of the cube after the collision is also unknown. The kinetic energy lost during the collision and the final landing positions of both objects are also being questioned. The solution involves calculating the impulse, velocity, speed, direction, and kinetic energy using the given information and a graph provided in the attachments.

10) A 5 kg ball sits motionless at the edge of a 2m long 1.2m tall table. A cube of mass 0.5kg plows into it head-on at a speed of 26m/s

There is a graph below in the attachments about the collision.



a) Determine the total impulse given to the ball. b) Determine the velocity of the ball immediately after collision. c) Determine the speed and direction of the cube immediately after collision. d) Determine the KE lost during collision. e) Determine where each of the two objects lands on the floor after collision.

a) Ft=mv Ft=.5(26) Ft=13 right?
b-e?


UPDATE: After conferring with classmates I've figured it out...no need for help =) thanks!

Question

I have the same question. Can someone explain how to go about solving this?
thanks.

a) impulse = force*time. The area of the graph under the function = 20 Newtons*sec.
 

1. What is impulse in physics?

Impulse is the change in momentum of an object due to a force applied over a certain period of time. It is represented by the equation Impulse = Force x Time, and it is measured in Newton-seconds (N-s).

2. How is impulse related to momentum?

Impulse is directly related to momentum, as it is the change in an object's momentum. The greater the impulse applied to an object, the greater its change in momentum will be.

3. What is the relationship between impulse and force?

There is a direct relationship between impulse and force. The greater the force applied to an object, the greater the impulse will be. This means that a larger force will result in a larger change in momentum.

4. How does impulse affect the motion of an object?

Impulse can affect the motion of an object in two ways. First, it can change the velocity of an object by altering its momentum. Second, it can also change the direction of an object's motion by changing its momentum vector.

5. How is impulse calculated?

To calculate impulse, you can use the equation Impulse = Force x Time. The force should be in Newtons (N) and the time should be in seconds (s). Alternatively, if the force is not constant, you can also use the equation Impulse = Change in Momentum.
