Question

The position of a particle moving in the
XY-plane at any time 't' is given by x = (3t^2-6t)
m; y (t^2-2t) m. Select the correct
Statement about the moving 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 = 0
second
3) The velocity of the particle is zero at t= 1
second
4) The velocity and acceleration of the
particle are never zero​

Answer 1

Answer:

(3)The velocity of the particle is zero at t= 1

second

Explanation:

x = 3t²-6t

y= t²-2t

velocity

v(X) = 6t - 6

v(y) = 2t - 2

verify option 3.

at t= 1s

v(X) = 0

v(y) = 0
