AIIMS 2010 Physics Motion in Two Dimensions MCQ Question
The position of a particle moving in the x-y plane at any time t is given by: x = (3t² - 6t) metres; y = (t² - 2t) metres. Select the correct statement.
acceleration is zero at t = 0
velocity is zero at t = 0
velocity is zero at t = 1s
velocity and acceleration of the particle are never zero.
Correct Answer
Detailed Explanation
x = 3t^2 - 6t; So (velocity)x = dx/dt = 6t - 6.
