The x and y displacementof a particle in the x-y plane at any instant are given by x=alphaT^(@) and y=2alphaT where a is a constant. The velocity of the particle at any instant is given by:

The x and y displacementof a particle in the x-y plane at any instant

1.	The x and y displacementof a particle in the x-y plane at any instant are given by x=alphaT^(@) and y=2alphaT where a is a constant. The velocity of the particle at any instant is given by:
Answer» `4asqrt(T^(2)+4)` `2asqrt(T^(2)+1)` `4asqrt(T^(2)+1)` `(a)/(2)SQRT(T^(2)+4)` SOLUTION :`v=sqrt(((dx)/(DT))^(2)+((DU)/(dt))^(2))`
