The co-ordinates of a moving particle at any time t are given by x = αt^3 and y = βt^3. The speed of the particle at time t is given by

Question 1

The co-ordinates of a moving particle at any time t are given by x = αt3and y = βt3. The speed of the particle at time t is given by

(1) 3t√(α2 + β2)

(2) 3t2√(α2 + β2)

(3) t√(α2 + β2)

(4) √(α2 + β2)

Question 2

Answer is (2) 3t2√(α2 + β2)

νx = dx/dt = 3 ∝ t2. or νy = dy/dt = 3βt2.

ν = √(ν2x + ν2y) = 3t2√(α2 +β2)

Answer is (2) 3t2√(α2 + β2)

νx = dx/dt = 3 ∝ t2. or νy = dy/dt = 3βt2.

ν = √(ν2x + ν2y) = 3t2√(α2 +β2)
