Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

Please be especific in every step.

e.g. A flywheel (radius 0.2m) is rotating with angular
speed 150r min-¹. Now it is braked and after 30 s stops.
(1) what are the angular acceleration and the turns
during the time? (2) the angular speed when t = 6 s ;
(3) t = 6 s, the line speed, tangent acceleration and

(B) llllllll Students set up an experiment by attaching an ideal vertical spring to a support and hanging a block of known mass from the spring. The students pull the block down and release it from rest. The students then measure the period of the block's oscillation. This procedure is repeated for several trials using the same spring but with blocks of different known masses. The students are instructed to create a linear graph using the mass m of each block and the period T of the block's motion. The slope of the graph will be used to calculate the force constant k of the spring. Which of the following best indicates how the students should create their linear graph and how k can be calculated from the slope of the graph? E k Graph T on the vertical axis and m on the horizontal axis; set k = 2π slope Graph T² on the vertical axis and m on the horizontal axis; set k Graph T on the vertical axis and m² on the horizontal axis; set k Graph T² on the vertical axis and m on the horizontal…

If the elevator cable should break when the elevator is at a height of 103m above the top of the spring, calculate the value that the spring stiffness constant should have so that passengers undergo an acceleration of no more than 3.9g when brought to rest. Let 924kg be the total mass of the elevator and passengers.
