A coordinate axis system taking x-axis as horizontal smooth floor is shown in figure. Two small balls of masses m and 3m attached with a string are released from some heights on y-axis as shown in figure. The balls may collide head on or obliquely. After a certain time mass m is at (9cm,20cm) while mass 3m is 25cm above the x axis and the strings is taut. The balls always remain in x-y plane. Find the length of string.

A ball is released from rest relative to the elevator at a distance h1 above the floor. The speed of the elevator at the time of ball release is v0. Determine the bounce height h2 relative to elevator of the ball (a) if v0 is constant and (b) if an upward elevator accleration a=g4 begins at the instant the ball is released. The coefficient of restitution for the impact is e = 2/3.

A 5 kg sphere is connected to a fixed point O by an inexistensible string of length 5 m . The sphere is resting on a horizontal surface at a distnce 4 m from O. sphere is given a vertical velocity v0 and it moves freely till it reaches point p, when string becomes taut. Find the maximum allowable velocity v0 , if impulse of tension in string is not to exceed 6 N s.
