i'm afraid you are going to have to experiment on that one as you will need to find out the centre of mass of the bowling pin. The centre of mass will be on the axis of the pin but the height will depend on how top or bottom heavy the club is. See page 8 of this guide to find out how to locate the centre of mass and to read up on falling over. http://www.mastep.org.na/PhysSc/IGCSEPSc/Forces.pdf Assuming the bowling pin is of uniform density then you could use cardboard cut to a flat bowling pin shape to locate the height of the centre of mass. This would be easiest. An object will topple when a line drawn from the centre of mass vertically downwards does not pass through its base. The angle between the base of the pin and the ground when this happens will be 90 degrees – the angle for which the tangent equals (height of centre of mass (h)) divided by (radius of the base of the bowling pin(w))
