Question

A particle reaches its highest point when it has covered exactly one half of its horizontal range. The corresponding point

on the displacement time graph is characterised by​

Answer 1

Answer:

At the highest point projectile motion, the tangent drawn is parallel to x-axis. Hence, slope at this point is zero. Moreover, the curve is convex upwards, hence curvature is positive at this point.

Answer 2

Explanation:

A car and motorcycle racing from rest along a runway the motorcycle take lead first but then car overtake motorcycle .The motorcycle first take lead because it has acceleration 8.40 m/s²,greater than car acceleration 5.60 m/s² but motorcycle looses to car because motorcycle reaches its greatest speed 58.8 m/s before car reaches its greatest speed 106 m/s
