Question

The angular velocity is positive and the angular acceleration is negative. The angular velocity is negative and the angular acceleration is positive. For a marble rolling at a constant speed through the interior of a hemispherical bowl (half of a sphere), the direction of the total acceleration is In the direction of the vector sum of the gravitational acceleration and the radial acceleration. Towards the centre of the circle. In the direction of the vector difference of the gravitational acceleration and the radial acceleration. Straight down. From the figure provided, which has/have the largest centripetal acceleration?
