A large wedge with a mass of 10 kg rests on a horizontal frictionless surface, as shown.A block with a mass of 5.0 kg starts from rest and slides down the inclined surface of the wedge, which is rough.At one instant the vertical component of the block's velocity is 3.0 m/s and the horizontal component is 6.0 m/s.At that instant the velocity of the wedge is:
A)3.0 m/s left
B)3.0 m/s, right
C)6.0 m/s, right
D)6.0 m/s, left
E)17 m/s, right
