Imagine a point mass m1 collides a mass m2 and m2 is at rest.In what condition the final velocity of two masses,will be prependicular to each other?

What happens when two masses collide and one is at rest?

In summary, the conversation discusses a collision between two masses, one of which is at rest. The question is posed about the final velocity of the masses and whether it will be perpendicular to each other. The formulas for energy and momentum are mentioned and it is suggested to write the momentum formula twice, for the x and y directions separately, and create two systems of equations to solve the problem.

I just have the formulas relating the magnitude of final and initial velocities in one dimension but,as you can see,this problem is two dimensional.

yes, the energy formula is one-dimensional,
but the momentum formula is a vector formula, so it's as many dimensions as there are …
in this case, you can write the momentum formula twice, for the x and y directions separately …

what do you get?

And then make two systems of equations one with energy equation and x momentum equation and one with energy equation and y momentum equation?

it's not really two systems, it's just three equations …
try it and see!
FAQ: What happens when two masses collide and one is at rest?
What is a collision?
A collision is a physical event in which two or more objects come into contact with each other. This can result in a change in motion or deformation of the objects involved.
What causes collisions?
Collisions can be caused by a variety of factors, including the movement and velocity of the objects, the surface properties of the objects, and the forces acting on the objects.
What are the types of collisions?
There are two main types of collisions: elastic and inelastic. In an elastic collision, the total kinetic energy of the objects involved is conserved, while in an inelastic collision, some of the kinetic energy is converted into other forms of energy.
How are collisions studied in science?
Scientists use various tools and techniques to study collisions, including high-speed cameras, computer simulations, and mathematical models. They also conduct experiments to gather data and analyze the results.
How can collisions be prevented?
In certain situations, collisions can be prevented by implementing safety measures such as speed limits, barriers, and warning signs. In other cases, collisions can be avoided by adjusting the trajectory or velocity of objects in motion.
