A 6.0 kh block, sliding to the east across a horizontal, frictionless surface with a momentum of 30 kg*m/s^, strikes an obstacle. The obstacle exerts an impluse of 10 N*s to the west on the book. The speed of the block after the collision is...

1. Given

m = 6 kg
p = 30 kg*m/s
J = 10 n*s

J = Fnet t

I know you cant use the p = mv since this states impluse.
