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