Amerry-go-round with a a radius of r = 1.63 m and moment of inertia i = 196 kg-m2 is spinning with an initial angular speed of ω = 1.53 rad/s in the counter clockwise direection when viewed from above. a person with mass m = 73 kg and velocity v = 4.2 m/s runs on a path tangent to the merry-go-round. once at the merry-go-round the person jumps on and holds on to the rim of the merry-go-round.
