KIND OF AN EMERGENCY! No links please! In the game of tetherball, a 1.25 m rope connects a 0.750 kg ball to the top of a vertical pole, so that the ball can revolve around the pole, as shown in the diagram.
a) Apply Newton's second law to calculate the tension in the rope
b) Calculate the speed of the ball as it rotates around the pole.
c) As the ball passes one of the players, the player slaps the ball to exert a force on the direction in which the ball was moving. Explain why the angle between the rope and the vertical increases.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
