The position(x)-time(t) graph of a ball is a straight line inclined at an angle of 30° to the x-axis. The ball is moving with:
The position-time (x-t) graph of an object represents its motion over time. The slope of this graph gives the velocity of the object.
If the graph is a straight line, it means the motion is uniform (constant velocity).
The slope of the line (the angle with the time axis) indicates the rate at which the position of the object is changing with respect to time.

A point mass has a velocity v = (1.0 m/s) i + (3.0 m/s) j, at a certain instant. At the same instant, it experiences a force F = - (2.0 N) i + (4.0 N) j + (5.0 N) k. i, j and k are unit vectors along x-, y-, and z- axis, respectively. The power delivered by the force, at that instant is:
