At time to = 0, particle A is released from rest at a height h = 10 m and falls down%3Dvertically under the effect of the regular force of gravity as shown in the figure. At the sametime t, = 0, particle B is launched from the ground level with a speed v, = 21 m/s at adistance x, = 15 m from where the vertical trajectory of particle A crosses the horizontal,as shown in the figure. Ignore air resistance.ho0.В(a) Determine the angle 0 at which particle B must be launched for it to collide withparticle A. The location of the collision is illustrated in the figure by the crossing ofthe dashed lines.
