The co–ordinates of a moving particle at any time t are given by x = αt3 and y = βt3. The speed of the particle at time t is given by
- \(3 \mathrm{t} \sqrt{\alpha^{2}+\beta^{2}}\)
- \(3 t^{2} \sqrt{\alpha^{2}+\beta^{2}}\)
- \(t^{2} \sqrt{\alpha^{2}+\beta^{2}}\)
- \(\sqrt{\alpha^{2}+\beta^{2}}\)
Answer
(B) 3 t^ 2 ^ 2 + ^ 2
