An object is moving in the x-y plane with the position as a function of time given by `vecr = x(t)hati + y(t)hatj`. Point O is at `x = 0 , y = 0` . The object is definitely moving towards O when

An object is moving along the x axis with postion as a function of time given by x =x(t) . Point O is at x = 0 . Object is definitely moving towardr O when

An ant is moving in x-y plane with its position vector vecs=2t^2hati+5hatj then, velocity vector of it at t = 1 sec is:

An object moves in such a way that its position (in meters) as a function of time (in seconds) is vecr=hati+3t^(2)hatj+thatk . Give expressions for (a) the velocity of the object and (b) the acceleration of the object as functions of time.

The position of a particle moving in x-y plane changes with time t given by vecx= 3t^2hati + 9thatj . The acceleration of particle would be

If x and y co-ordinates of a particle moving in xy plane at some instant of time are x = t^(2) and y = 3t^(2)

An object is moving in x-y plane its velocity and acceleration at t=0 are represented in figure. After how much time object crosses the y- axis:-
