Problem
On the horizontal surface of a flat table, the co-ordinates, in cm, of a ball change uniformly from (1, -1) to (5, 5) during a time of 4.0 s.
(1) Calculate the magnitude of the overall displacement of the ball.
(2) Calculate the average speed of the ball.
(3) By writing the overall displacement of the ball as the x - and y -components of a vector, calculate the angle to the x -axis of the motion of the ball.
(4) State the velocity of the ball during the 4.0 s period.
