conservation of momentum
intial momentum=final momentum
2.87*4.87i +1.96*(-2.55)j=(2.87+1.96)V
13.97i - 5j=4.83 V
solve for V. I used i,j instead of x,y
A 2.87 kg object initially moving in the positive x-direction with a velocity of +4.87 m/s collides with and sticks to a 1.96 kg object initially moving in the negative y-direction with a velocity of -2.55 m/s. Find the final components of velocity of the composite object. (Indicate the direction with the sign of your answer.)
