In the instant shown, block A is moving at 3.5 m/s up the ramp, while block B is moving at 1 m/s down the ramp. The blocks collide at a point 0.2 m from the original position of B as shown. And the impact is assumed to be has e = 0.8. Block A has a weight of 8 N and that of Block B is 12 N. Calculate the following: 

(a) The velocity of A just before impact, VA1

(b) The velocity of B just before impact, VB1

(c)  The velocity of A just after impact, VA

(d) The velocity of B just after impact, VB2

(e) The value of the impulse
