A particle starts from the origin of coordinates at time t=0 and moves in the xy plane with a constant acceleration α in the y-direction. Its equation of motion is y=βx^2. Its velocity component in the x-direction is

The coordinates of a particle moving in x-y plane at any instant of time t are x=4t^2; y=3t^2. The speed of the particle at that instant is :
