A particle moves in a straight line where its position vector ⇀x (meter) is given as a function in the time t (sec.) by the relation ⇀x = cos t ⇀c where ⇀c is a unit vector in the direction of motion of the body. Then the body passes through the origin point for the first time after time...........sec
