Answer» Given INFO : motion of PARTICLE is given as To find : angle made by DISPLACEMENT with the X - axis at t = 3 sec Solution : at t = 3 sec, displacement of particle along x - axis is x = (3)² + (3) + 4 = 9 + 3 + 4 = 16 m displacement of particle along y - axis is y = 4(3) = 12 m so, displacement of particle at t = 3 sec is (16 i + 12 j) m. Angle made by displacement with x - axis = tan¯¹ (y/x) = tan¯¹ (16/12) = Tan¯¹(4/3) Therefore the angle made by displacement with x - axis is tan¯¹(4/3). also read similar questions : The position of a body moving along x-axis at time to is given by x = (t^2 - 4t +6)m.
