35 A train moves at 15 0 m s in the x direction A child on the train drops a ball out the window with zero initial y component of velocity From the child s point of view the ball falls straight down to the ground An observer standing on the ground also watches the ball drop She observes that the ball hits the ground 12 0 m along the x axis ahead of the drop point Neglect friction 15 m s 12 m a From what height above the ground was the ball dropped b According to the ground observer what is the instantaneous velocity vector v of the ball just before it hits the ground Express v in terms of unit vectors i and j c According to the ground observer what is the average velocity vector Vay of the ball over the time of its fall Express Vav in terms of unit vectors i and j d According to the ground observer what is the average acceleration vector aav over the time of its fall Express aay in terms of unit vectors
