Important Questions on Kinematics


Two skaters, and are skating towards each other. Skater, throws a ball towards, every such that it always leaves her hand with speed with respect to the ground. Consider two cases: (I) runs with speed towards while remains stationary. (II) runs with speed towards while remains stationary. Note That irrespective of speed of ball always leaves s hand with speed with respect to the ground. Ignore gravity. Balls will be received by


In the cube of side shown in the figure, the vector from the central point of the face to the central point of the face will be:
