Question

A particle moves so that its position as a function of time in MKS unit is r=i+4t2j​+tk. The trajectory of the particle is  ​

Answer 1

Answer:

Correct answer is Aparabola

Given,

r = 1 + 4t² + tk

From the above equation,

x = ct

X C t -

y = 4t²

X = 4(²) ² y = 4( -

y = 4 (2)x²

This is the equation of a parabola. The correct option is A.
