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.
.

Verified by Experts

`t_(1)=(AB)/(s) =((pi)/(2)(r)/(s)), t_(2) =(BC)/(2 S) =((2pi)/(3)r)/(2s)`
` t_(3)=(CA)/(3s)=((5pi)/(6)r)/(3s)`
.
Average speed `=(2pir)/(t_(1)+t_(2)+t_(3)) =1.8 s`.

(i) The acceleration (a) of a particle moving along a straight line is related to time (t) as per the differential equation (d^(2)a)/(dt^(2))=-ba. b is a positive constant. Is the particle performing SHM? If yes, what is the time period? (ii) A particle is executing SHM on a straight line. A and B are two points at which its velocity is zero. It passes through a certain point P (AP gt PB) with a speed of 3 m//s at times recorded as t = 0, 0.5 s, 2.0 s, 2.5 s, 4.0 s, 4.5 s......Determine the maximum speed of the particle and also the ratio AP//PB .

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 D where particle finally strikes. Acceleration due to gravity g=10m//s^(2) Time taken by the particle to reach the ground is
