For a body moving along a coordinate line it is required to determine the following from the graph given below:
Part a) The time when the body reverse direction.
Part b) The time when the body is moving with a constant speed.
Part c) Speed-time graph for the body on the time interval 0 to 10 seconds.
When a body moving along a coordinate axis changes its direction the sign of the velocity changes.
Observe form the velocity-time graph given below that the velocity of the body changes from positive to negative at the point x = 2 and from negative to positive at the point x = 4.
When the body is moving with a constant speed the velocity-time graph of the body is a straight line parallel to the x-axis.
Observe that t...
