1. A girl tied a toy plane on a string which she rotated to form a horizontal circle of radius 15X cm. The plane of the circle is 120 cm above the ground. When the string breaks, the plane hits another toy on the ground which is 1.2x m away from the feet of the girl. Find the radial acceleration of the plane during its circular motion. 1. Given: X: 1.56 Radius =15X cm =15(1.56) = 23.4 cm Ax = 1.2x m =1.2(1.56) = 1.872 m Ay = 120 cm
