Question:
Figure shows a man sitting in a bosun's chair that dangles from a mass less rope, which runs over a mass less, frictionless pulley and back down to the man's hand. The combined mass of man and chair is 95.0 kg. With what force magnitude must the man pull on the rope if he is to rise
(a) With a constant velocity and
(b) With an upward acceleration of 1.30 m/s2? If the rope on the right extends to the ground and is pulled by a co-worker, with what force magnitude must the coworker pull for the man to rise
(c) With a constant velocity and
(d) With an upward acceleration of 1.30 m/s2? What is the magnitude of the force on the ceiling from the pulley system in?
(e) Part a,
(f) Part b,
(g) Part c, and
(h) Partd?

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
