Question
If you could create example problems from the information provided and show the work that would be amazing thank you! Feel free to make up any numbers you need to I just need to understand the concepts There was one that was like at terminal velocity what is the magnitude of the drag force There was one that a man used a pulley to lift a box 2m, tension was 65 and it was asking for net work I think it gave the mass of the box too One had a box on a horizontal,a pulley and a hanging mass and it gives you the us and you have to determine the heaviest weight you can put as the hanging mass without the boxes moving There was one about a Ferris wheel and it said a 40 kg /3 passenger sits in a seat at the bottom of the wheel, what is the force of the seat pushing up on the rider A hockey puck is thrown on a horizontal surface and travels 6m. The uk was 0.25 and you had to find the initial velocity with the work energy theorem There are two more I don't rememberExplanation / Answer
1. A rain drop of radius 0.5 mm falls through air with terminal velocity of 2 m/s. The viscosity of air is 20*10-5 poise. Find the viscous force acting on the rain drop.
2. A box of mass 25 kg is pulled up by a man of mass 60 kg through a pulley hanging little high above the man's height through a vertical support. While pulling, the tension in the rope over the pulley is 100 N. Find the amount of work done by the man on the box if he pulls it thorugh a distance of 1.5 m.
3. A block of mass 10 kg is resting on a smooth horizontal surface and is connected to a string which passes over a frictionless pulley and carries a mass M at the other end. What is the largest value of M such that the system doesn't move?
Hint: In the first question, you apply Stokes' law equation and net force on rain drop is zero as it is moving with terminal or final constant velocity.
In the second question, apply the definition of work done.
In the third question, make free body diagrams of both masses and from there, put net force on each block to be zero.
