Relative Velocity in Rotational Motion
A merry-go-round rotates at a constant angular velocity ω. At a distance r from the center, a student throws a ball with velocity v₀, directed radially outward relative to the merry-go-round. What is the initial velocity of the ball as measured by a stationary observer on the ground?
A
v₀ radially outward
B
√(v₀² + (rω)²) at an angle with the radial direction
C
v₀ radially outward - rω tangentially
D
v₀ radially outward + rω tangentially
