A bullet of mass m hits a disc of radius R on its periphery at speed v.What will be the velocity of disc if the collision is inelastic?
You tell us. Hint: What's conserved?satishinamdar said:A bullet of mass m hits a disc of radius R on its periphery at speed v.What will be the velocity of disc if the collision is inelastic?
The problem statement does not give all the needed information. Is the disk at rest? What is its mass? This almost sounds like it could be a rotation problem. Is there more you have not told us?satishinamdar said:momentum is conserved.pl help
There are different ways that a collision can be inelastic. The bullet could compress and deflect off. The bullet could stick to the disc. Since the question does not give you the final speed of the bullet, let's assume that it sticks to the disc. In this case, the question is asking for the velocity of the centre of mass of the disc + bullet and this is just a matter of applying conservation of linear momentum:satishinamdar said:A bullet of mass m hits a disc of radius R on its periphery at speed v.What will be the velocity of disc if the collision is inelastic?
Why do you insist on not stating the problem? You have been asked to do it repeatedly. You still have not given us enough information to find a result. If you want help, state the problem exactly the way it was given to you.satishinamdar said:it is fixed to axis.Angular speed to be calculated.
One has to assume the disk is perpendicular to the path of the bullet, the bullet strikes at a distance R above the horizontal axis about which the disk rotatates and sticks to the disk.matthew baird said:"THE ARROW TOUCHING THE CIRCLE PERIPHERY TANGENTIALLY"
Once again I am tired, is the arrow hitting the face of the circle as a real arrow strikes a target, or the arrow somehow sticks on the edge of the circle , as if a car wheel was hit with a falling rock on the edge and caused it to spin?
You have been provided with all the hints you need: See my last post and Andrew's post. Now it's your turn.satishinamdar said:Dear Guruji
the problem as appearing in the textbook is as follows
"A bullet of mass m collides inelastically at the periphery of a disc of mass M and RADIUS r, with a speed v.The disc rotates about a fixed horizontal axis.Find theangular velocity of the disc bullet system just after the impact."
Now I request you to help.
A bullet hit disc is an experiment where a bullet is fired into a stationary disc, causing it to rotate. An inelastic collision is a collision where the kinetic energy is not conserved, meaning some of the energy is lost in the form of heat, sound, or deformation.
The velocity of the bullet plays a significant role in the results of the experiment. A higher velocity bullet will have more kinetic energy, causing a larger amount of energy to be transferred to the disc and resulting in a higher rotation speed.
The mass and size of the bullet and disc can also affect the outcome of the collision. A heavier bullet or a larger disc will have a greater impact and result in a higher rotation speed. Additionally, factors such as friction and air resistance can also affect the results of the experiment.
The velocity of the bullet and the resulting rotation speed of the disc are directly proportional. This means that as the velocity of the bullet increases, the rotation speed of the disc will also increase.
This experiment can be used to study the effects of inelastic collisions in real-life scenarios, such as car accidents or sports collisions. It can also help engineers design better safety measures to reduce the impact of collisions and prevent injury.
