Homework Statement
Mass of 2m slides on a horizontal plane with the velocity of v0 across the x-axis. And hits the mass m which is in rest. after the collision mass m moves with the velocity of v0/2 in the direction which creates an angle of 30 degrees of the original movmen of 2m.
a) What is the velocity of mass 2m after the collision?
b) What is the direction of mass 2m after the collision?
c) Is the collision described is perfectly ellastic collision?
Homework Equations
P=m*v
Pi=Pf
The Attempt at a Solution
I have broken down the velocity to x,yPinitialx=Pfinalx
m1*V1ix+m2*V2ix=m1*V1fx+m2*v2fx
2m*v0+m*0 = 2m*Vfcosθ+m*v0/2*cos30Pintialy=Pfinaly
m1*V1iy+m2*V2iy=m1*V1fy+m2*v2fy
0 = -2m*Vfsinθ+m*V0/2sin30
I don't know what to do from here. i can't simplfy the equations,
could you help me with that?
Thank you,
