A problem of uniform circular motion in Physics Under the action of external force, particle a moves in a clockwise circular motion with uniform velocity in the vertical plane. The orbit radius is r, and point P is the highest point in the vertical plane. When particle a passes through point P, a particle B just moves from point P with the velocity v = Gr / 2 (there is an open radical outside, starting to do horizontal throwing motion. After a period of time, two particles collide, Solution: the acceleration of particle A in uniform circular motion. (the acceleration of gravity is g)

Because the initial velocity of horizontal projectile V0 = √ (GR / 2) x = v0t H = GT ^ 2 / 2, when x = R, H = R, the trajectory of horizontal projectile intersects with the uniform circular motion trajectory when it falls R, and the time just passes t = R / v0
