A rope 10 m long is stretched between a tree and a car. A man pulls with a force of 10 N at right angles
to ang at the middle of point of the rope and moves this point 0.5m. Assuming no stretching of the
rope (theoretical), what is the tension in the rope at the final position?

A block of mass mA=20kg on an inclined plane and a bucket of mass m(bucket)=15kg are attached to the ends of a massless string passing through a massless pulley as shown in the figure below. The inclined plane makes an angle of TETA=44 DEGREE with the horizontal and the coefficients of kinetic and static friction are μk=0.25 and μs=0.6. The system is initially at rest and a student starts to fill the bucket with balls, each of whose mass is 100 grams, one at a time until the system starts to move. Determine the number of balls the student placed in the bucket. Take g=9.80m/s2 and please note that the number balls must be an integer!
A 10.0 kg mass hangs from a rope, as shown in the figure. The rope passes over a fixed pulley, then under a movable pulley, and is attached to the ceiling as shown. The movable pulley has a mass m attached to it and moves at a constant speed. Find the tension in the rope. Assume that the masses of the pulleys are negligible.
