Q2. alice is in the middle of a merry-go-round (carousel) of radius r. bob watches from the side while alice rotates on the merry-go-round. alice throws a ball of mass m radially outwards with speed v, while she rotates with constant angular velocity ω. alice and bob talk afterwards and she tells him how she saw the ball be deflected to the side, as if it were acted upon by some force. bob explain this inertial force to alice by identifying both frames of reference and showing that this inertial force (known as the coriolis force) has a magnitude of 2mωv
