Question

draw the position time graph for motion of a body moving along the positive x axis with positive acceleration .what is the value of acceleration of a projected body at its highest point

Answer 1

$x=1/2 gt^{2}$

For a projected body, at the highest point acceleration would be measured as g(-j). From the time graph (draw between time, t and positive x axis), the motion of body along the positive x axis has been determined well.

The value of acceleration keep raising upward to touch highest point.
