A ping pong ball was dropped inside the bowl and was at rest initially then a person pushed the ping pong ball causing the ball to roll and also allowing the ball to not slip while rolling. By knowing that the ping pong ball is solid and has a radius of “r” and letting the “R” be the bowl radius, find the speed of the ping pong ball as it passes through the lowest point of the bowl as shown in figure where it starts from θ measured from the dotted vertical line through the center of the bowl without the ping pong ball slipping inside of the bowl.
