SOLVE STEP BY STEP IN DIGITAL FORMAT 36.- The flywheel of an engine has a moment of inertia of 2.50 kgm^2 around its axis of rotation. a) What constant torque is required for it to reach an angular speed of 400 rpm in 8.00 s, starting from rest? b) What is its final kinetic energy?

Flywheels are large, massive wheels used to store energy. They can be spun up slowly, then the wheel's energy can be released quickly to accomplish a task that demands high power. An industrial flywheel has a 1.5 m diameter and a mass of 250 kg. A motor spins up the flywheel with a constant torque of 50N⋅m50N⋅m. How long does it take the flywheel to reach top angular speed of 1200 rpm?   Show a diagram

Starting from rest, a 10.8cm diameter compact disk takes 7.96s to reach its operating rotational speed of 1920.0 rpm (revolutions per minute). Assume that the angular acceleration is constant. The disk's moment of inertia is 3.88E-5kg.m². How much torque is applied to the disk? Submit Answer Tries 0/10 How many revolutions does it make before reaching full speed? (Do not enter a unit.)

What is the moment of inertia ? of an object that rotates at 14.0 rev/min about an axis and has a rotational kinetic energy of 24.0 J?

Arithmetic question. Write only the final value of the answer.   Suppose you did the rotational dynamics labs with a 200g solid sphere. The sphere was placed at rest at the 100cm mark on the track which is inclined at 150 angle with the table. What is the translational kinetic energy in (J) of the sphere as it leaves 0 mark of the track? Write your answer with TWO decimal places.

A wheel has a radius of 0.1m and a moment of inertia of 4.00 kg-m2 starts from rest and accelerates under a constant torque of 12.0 N-m for 4.00 s. a) What is the wheel’s rotational kinetic energy at the end of 4.00 s? b) How far has the wheel rolled at the end of 4.00s?

A 5kg sphere with a radius of 10 cm is spinning at an angular of 15rads/s. What is the rotational kinetic energy (in j) of the solid sphere? The final answer in 2 decimal places
