A) 8 ft./ sec. right;
B) 36.6 degrees;
V c = 10.39 ft/sec;
Vd = 8.72ft. sec;
Here also we will use the conservation of linear momentum. Ball A is moving with a velocity v= 16ft/s and it imparts some of this momentum to B and after the collision, since the pieces moves at some angles, we will write,
m * 16 = [mb * vf] + m * va
(vf is the velocity of the mass B if it were unbrocken and va is the final velocity of mass A)
from the ...
The conservation of linear momentum is analyzed.
