A cart is moving alongs +ve x-direction with a speed of 4m/s Aperson on the cart throw a stone with a velcity of 6 m/s w.r.t hiumself In the frame of refrence of the cart the stone is thrown in the y-z palne making an angle of `30^(@)` with the verticle z- axies . Then w.r.t an observer on the ground

A cart is moving along +x direction with a velocityof 4 m//s . A person on the cart throws a stone with a velocity of 6 m//s relative to himself. In the frame of reference of the cart the stone is thrown in y-z plane making an angle of 30^@ with vertical z-axis. At the highest point of its trajectory, the stone hits an object of equal mass hung vertically from the branch of a tree by means of a string of length L. A completely inelastic collision occurs, in which the stone gets embedded in the object. Determine : (i) The speed of the combined mass immediately after the collision with respect to an observer on the ground,
