Question

the position of the particle moving in xy plane at any time t is given by X = (3t square - 6t) metres y =( t square - 2t) meter select the correct option about the following particle from the following 1) the acceleration of the particle is zero at t=0 second 2) the velocity of the particle is zero at t = 0seconds 3) the velocity of the particle is zero at t 1 seconds 4) the velocity and acceleration of the particle are never zero​

Answer 1

Answer:

right option is 3rd

Explanation:

you get velocity of body in x and y direction by differentiating position equation with respect to time

velocity in x =6t-6

velocity in y =2t-2

velocity becomes 0 when t=1

you get acceleration by differentiating velocity equation with respect to time

acceleration in x = 6

acceleration in y= 2

since acceleration is constant so it never be zero
