Teaching HSSC TGT 2023 Mock Test (Latest Pattern) Physics Motion in Two and Three Dimensions Average Velocity and Instantaneous Velocity
The co-ordinates of moving particle at any time t are given as x = αt3 and y = βt3. The Speed of the particle at t is given by – (where the letters have their usual meanings)
1
\(3t\sqrt {{\alpha ^2} + {\beta ^2}}\)
2
\(3{t^2}\sqrt {{\alpha ^2} + {\beta ^2}}\)
3
\({t^2}\sqrt {{\alpha ^2} + {\beta ^2}}\)
4
\(\sqrt {{\alpha ^2} + {\beta ^2}}\)
