A large heavy box is sliding without friction down a smooth plane of inclination θ. From a point P on the bottom of the box, a particle is projected inside the box. The initial speed of particle with respect to the box is u and the direction of projection makes an angle α with the bottom as shown. Find the distance along the bottom of box between the point of projection P and point Q where the particle lands. (Assume that the particle does not hit any other surface of the box. Neglect air resistance)

Two towers AB and CD are situated at distance d apart as shown in Fig. AB is 20 m high and CD is 30m high from the ground. An object of mass m is thrown from the top of AB horizontally with a velocity of 10 m/s towards CD. Simultaneously, another object of mass 2m is thrown from the lay of CD at an angle 60 to the horizontal towards AB with the same magnitude of initial velocity us that of the first object. The two objects move in the same vertical plane, collide in mid-air, and stick to each other. a. Calculate the distance d between the towers. b. Find the position where the objects hit the ground.
