1. Suppose a person covers 300 m east, then 400 m southwest and 200 m at 30 degree north of west. (a) What is the magnitude of the resultant displacement? (b) What is the direction of the resultant displacement? 2. A ball rolls off a horizontal table with an initial speed of 6.5 m/s. The ball falls a vertical distance of 1.0 m into the floor below. (a) How much time does the ball spend in the air? (b) What is the y component of the velocity of the ball just before it strikes the floor? (c) What is the speed v of the ball just before it strikes the floor? (d) How far horizontally from the base of the table does the ball strike the floor
