ahh what is this question soo arrggghhhh
a body of mass 400g is moving along a smooth surface at a velocity of 10m s-1 east. it strikes a body mass 650g, initially at rest, and then the 400g body moves at a velocity of 8m s-1 in a direction E35 degree N. What is the velocity of the 650g object?
i assume it has something to do with vectors but please help me out here thanks you
