The tangenital acceleration of a particle in a circular motion of radius 2 m is a_(t)=alphat m//s^(2) (where alpha is a constant) initially the particle as rest. Total acceleration of the particle makes 45^(@) with the radial acceleration after 2 sec The value of constant alpha is :

Acceleration of two identical particles moving in a straight line are as shown in figure. If initial velocity of both the particles was zero. Then velocity of their centre of mass after 10 s will be
