Homework Statement
A child A is on a Merry Go Round that is turning at an angular velocity of 0.5 rad/s in the
clockwise direction. A ball B thrown from another child who is 4.5 m from the center of the MGR has a velocity of 10m/s and directly aimed at the center of the MGR as shown in the figure. Now, let us assume that the child A is running along the edge of the MGR at 0.4m/s in the clockwise direction with respect to the MGR. Find the velocity and acceleration of the ball seen from the child A.
Homework Equations
I know, W,A = W,MGR + W,A/MGR where W=angular velocity
And i belive, W,A/MGR = 2pi/(time for A to make one rotation)
The Attempt at a Solution
I am not sure how to calculate the time for A to make one rotation
