On a large circular horizontal track with radius r, without friction, there are two small balls with masses of my m, which can slide freely over the track. Between the two balls there is a compressed spring which, however, is not attached to the balls. The two balls are held together by a cord. (a) if the cord is broken, the compressed spring (which is assumed to be massless) will displace the two balls in opposite directions; The spring itself is left behind the balls collide when they meet again on the track. Where does this clash take place? Express the response in terms of the Angle, in radians, through which the ball travels m. (b) the potential energy initially stored in the spring was u_ {w} find the time that elapses from the moment the cord breaks until the collision happens. (C) assuming that the collision is perfectly elastic and frontal, where would the balls collide again after the first collision?
