A particle starting from the origin (0,0) moves in a straight line in the (x, y) plane. Its coordinates at a later time are ( 3 , 3) . The path of the particle makes with the x -axis an angle of

Step-by-step solution

Draw the situation as shown. OA represents the path of the particle starting from origin O(0,0) Draw a perpendicular from point A to x-axis. Let path of the particle makes an angle with the x -axis, then aligned & = slope of line O A & = A B O B = 3 3 = 3 or & =60^ aligned
