Shows a particle starting from point `A`,travelling up to `B` with a speed `s`, then up to point `C` with aspeed `2s`, and finally upto `A` with a speed of `3s`, Derermine its averagespeed.

A particle starts from rest and travels a distance 's' with uniform acceleration, then it travels a distance '2s' with uniform speed and finally it travels a distance '38' with uniform retardation and comes to rest. If whole motion is in a straight line, the ratio of maximum velocity to average velocity is

Starting from rest at s=0,a boat travels in a straight line with an acceleration on as shown by the a-s graph. Determine the boat's speed at s=40,90 .

There is a tower of height 20m and a particle is projected up from top of the tower with an initial speed 20m//s. Top of the tower is marked as point A, from where particle is projected. Point of maximum height a denoted as B. When particle reaches the point A during downward journey then we call the same point as C. Point at the bottom of tower is marked as Dwhere particle finally strikes. Acceleration due to gravity g=10m//s^(2) Maximum height above the ground attained by particle is
