Problem P. 3974. (April 2007)
P. 3974. A body of mass m1=2 kg slides down from the top of an inclined plane (the angle of inclination is =20o.) A cart of mass m2=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?
