A large box is given velocity u up the inclined plane and during its motion this box has acceleration 6 m/s2 down the inclined plane. At the time of projection of box a particle is also projected from point P with speed 10 m/s making an angle 74° with horizontal as shown in fig. Value of u so that particle hits the point Q (PQ=10 m)Diagram |
