S(x ,y)=0 represents a circle. The equation S(x ,2)=0 gives two identical solutions: x=1 . The equation S(1,y)=0 given two solutions: y=0,2. Find the equation of the circle.

The motion of a particle, along x-axis, follows the relation x = 8t- 3t^(2) . Here x and t are expressed in metre and second respectively . Find (i) the average velocity of the particle in time interval 0 to 1 s and (ii) its instantaneous velocity at t = 1 s.

If the ratio of the roots of the equation x^2-2px+q^2=0 be equal to the ratio of the roots of the equation x^2-2rx+s^2=0 , Prove that, p^2s^2=q^2r^2 .

The position of an object moving along x-axis is given by x=a+bt^(2) where a = 8.5 m, b = 2.5 m s^(-2) and t is measured in seconds. What is its velocity at t = 0 s and t = 2.0 s. What is the average velocity between t = 2.0 s and t = 4.0 s ?

Displacement s of a particle at time t is expressed as s=1/2t^3-6t . Find the acceleration at the time when the velocity vanishes (i.e., velocity tends to zero).
