# Problem P. 3974. (April 2007)

**P. 3974.** A body of mass *m*_{1}=2 kg slides down from the top of an inclined plane (the angle of inclination is =20^{o}.) A cart of mass *m*_{2}=1 kg is attached to this body with a thread of length =1.6 m as shown in the figure. The thread initially is straight. Along the first part of the slope, the length of which is /2, friction is negligible, along the second part, the length of which is /2, the coefficient of friction is =0.6. How far will the two objects be when the cart reaches the pulley?
