12–217. The crate C is being lifted by moving the roller at A downward with a constant speed of VA = 2 m/s along the guide. Determine the velocity and acceleration of the crate at the instant s = 1 m. When the roller is at B, the crate rests on the ground. Neglect the size of the pulley in the calculation. Hint: Relate the coordinates xc and xa using the problem geometry, then take the first and second time derivatives. - 4 m- B XA хс 4 m A
