The coordinates of a body moving in a plane at any instant of time are x= alphat^(2)= and y=betat^(2). The velocity of theboyd is |
|
Answer» SOLUTION :`x= alphat^(2) rArr v_(x)=(dx)/(DT)=2alphat` `y= beta t^(2) rArr v_(y)=(dy)/(dt)=2betya` `:. velocity V= sqrt(v_(x)^(2)+v_(y)^(2)) rArr sqrt((2 alpha t)^(2)+( 2 beta t)^(2))` `=2t sqrt(alpha^(2)+beta^(2))` |
