PHYSIC momentum QUESTION~
A billiard ball moving with velocity 4i+3j m/s strikes a stationary ball of the same mass. After the collision the struck ball moves with a speed of 4m/s at an angle of 30 degree with respect to the line of original motion of the striking ball. Find velocity of the striking ball after collision.
Pi=Pf
P=mv
Pxi=mv1=4
Pxf=mv2cos(theta)+m(4)cos30
Pyi=mv1=3
Pyf=mv2sin(theta)+m(4)sin30
am i correct with that?? i am really confuse
