A particle reaches its highest point when it has covered exactly one half of its horizontal range. What is the slope and nature of curvature at the corresponding point on the displacement-time graph?

Answer»

A particle REACHES its HIGHEST point when it has covered exactly one half of its horizontal range. At the highest point projectile MOTION, the tangent drawn is PARALLEL to x-axis. Hence, slope at this point is ZERO.
