Research on uniform circular motion When an object slides down with a smooth sphere, the velocity at the highest point is 2m / s, and the radius of the sphere is 3M? The answer is that the angle between the object and the center of the circle is 37 degrees
v=2+√2gh
g*cosα=(v∧2)/3
h=3-3*cosα
Three equations can solve H (the vertical distance from the highest point to the separation point)
