## Homework Statement

Question: A body of mass M1=m moving with a velocity V1=v in the x-direction collides with another body of the same mass m2=m moving in the y-direction with the same speed V2=v The coalesce into one body during collision

## Homework Equations

(a) Find the magnitude of the momentum of the composite body

(b)The angle which the direction of the momentum vector of the composite body makes with the x-axis

(c) The fraction of the kinetic energy transformed into heat during collision

## The Attempt at a Solution

For finding the momentum is it Just P=mv ?

I don't know the formula for finding the direction of momentum

and, Do we use the formula K.E=1/2 mv^2 or K.E=1/2 Iw^2

I Have high expectations and Hopes from this website :)
