Incompressible al flows The velocity distribution is) Ux = y + 3x+1
Ug = x - 3y+2
1. If the low has stream function? If yes find it
2. Find the velocity
potential

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
