64. The point P is displaced vertically by 2 R , where R is the radius of the wheel. It is displaced horizontally by half the circumference of the wheel, or π R . Since R = 0.450 m, the horizontal component of the displacement is 1.414 m and the vertical component of the displacement is 0.900 m. If the x axis is horizontal and the y axis is vertical, the vector displacement (in meters) is () ˆˆ 1.414 i + 0.900 j . r = G The displacement has a magnitude of
