Given:-
Position of an object moving in x-y plane, r=(3t²i+2tj)m
To Find:-
Acceleration of the object(particle) at t=2s
Solution:-
We know that,
Velocity of a body 'v' is given by
Acceleration of a body 'a' is given by
where,
x is the displacement or position of particle at time t
━━━━━━━━━━━━━━━━━━━━━
Let the velocity of given particle be v and acceleration of given particle be a
So,
Also,
At t=2 s
So,
Acceleration of given object is 6 m/s² in the direction of x-axis.
