How much time will it take for weight B to travel upward 242 mm? if point P has a constant acceleration of 650 mm/s^2 and Point P starts from rest. 

The diagram illustrates a mechanical pulley system involving several components: 1. **Component A**: - Diameter: 50 mm - Function: Acts as a small pulley with a belt that transfers rotational motion. 2. **Component C**: - Diameter: 150 mm - This larger pulley is connected to the smaller pulley (A) via a belt. It's attached to a drum (D). 3. **Point P**: - Indicates the direction in which the belt moves over the pulleys. 4. **Component D**: - The drum is part of the larger pulley (C) and has a rope that descends to a weight. 5. **Component B**: - A weight or load that is moved vertically. - The vertical distance moved by the weight is denoted by "s." 6. **Distances**: - The belt travels a distance of 75 mm between pulleys A and C. In this system, the rotation of the small pulley (A) drives the larger pulley (C) and consequently raises or lowers the weight (B) vertically, demonstrating principles of rotational motion, mechanical advantage, and load lifting using pulleys.
