Initially a 30kg child sits at the east edge of the stationary merry-go-round. A second child with a mass of 40kg runs north at a speed of 10km/hour, jumps and lands on the west edge of the merry-go-round making it turn.

a) Make a sketch of problem during the jump when the 40kg child is in the air traveling at 10km/h north indicating the

**linear momentum vector**(qualitatively only)

b) Make a sketch of the merry-go-round after it is turning indicating the angular momentum vector (qualitatively only)

c)Find the magnitude of the angular velocity vector of the turning merry-go-round.

c)Find the magnitude of the angular velocity vector of the turning merry-go-round.

I don;t expect anyone to sketch the first a and b problems

but it would help of you can tell me what what the linear momentum vector looks like.

i don't really understand the whole qualitatively part.

for c

i tried but i think i failed.

i used KE=p/2m

i got KE= 1.35 J

then used KE=IW^2/2

I=mr^2

so 1.35=((70)(2)^2)(W)/2

so W(angular velocity)= 0.00964rad/s

but im pretty sure i am soo wrong because its asking for

**magnitude**of the angular velocity. which is far from my thoughts.
