**Physics of Spool Mechanics**The spool of cable has a mass of \( m \) and a radius of gyration of \( k_c \). The tension in the cable \( T \) is a function of time \( t \), where \( t \) is in seconds. Neglect the mass of the unwound cable, and assume it is always at a constant radius.**Diagram Description:**The diagram illustrates a spool of cable resting on a horizontal surface. The spool has an outer diameter \( d_o \) and an inner diameter \( d_i \). A force due to tension \( T \) acts horizontally to the right on the cable wound around the spool.A coordinate system is implied with horizontal and vertical directions. The distance from the ground to the center of the spool is denoted as \( h \), and there is an angle \( \theta \) of 60° between the tension in the cable and the line perpendicular to the ground.**Parameters:**- Outer Diameter \( d_o = 1 \, \text{m} \)- Inner Diameter \( d_i = 0.5 \, \text{m} \)- Height \( h = 2.25 \, \text{m} \)- Radius of Gyration \( k_c = 0.77 \, \text{m} \)- Mass \( m = 100 \, \text{kg} \)- Tension in the cable \( T = 30t^3 + 77t \, \text{N} \)- Time \( t = 1.81 \, \text{s} \)- Force \( \vec{F} = 135t + 0j \, \text{N} \)**Exercises:**a) **Moment of Inertia of the Spool:** To find the moment of inertia \( I \) of the spool, we use the formula: \[ I = m k_c^2 \]b) **Angular Acceleration:** The angular acceleration \( \alpha \) of the wheel at time \( t \) can be computed using: \[ \alpha = \frac{\tau}{I} \] where \( \tau \) is the torque.c) **Cable Pulling Speed:** To determine how quickly the cable is being pulled at time \( t \),

Chapter 07, Problem 027 Z Your answer is partially correct. Try again. A spring and block are in the arrangement of the figure. When the block is pulled out to x = +4.0 cm, we must apply a force of magnitude 370N to hold it there. We pull the block to x = 11.0 cm and then release it. How much work does the spring do on the block when the block moves from x, = +5.0 cm to (a) x = +4.0 cm, (b) x = -4.0 cm, (c) x= -5.0 cm, and (d) x = -10.0 cm? x=0 Block F= 0 attached elleeee to spring (a) x positive F, negative (b) ugen/shared/assignment/test/aglist.uni?id=.. x negative 9:34 PM search A ENG 4/4/2021 ASUS 13) 1ghome f10 snd 17 4 7. 00 16 3.

A steel ball is tethered to the end of a cable. The ball is attached to a spinning axle that causes the ball and cable to rotate in a vertical circle counter-clockwise. The ball moves in a circle of radius R=.50 m centered at a height of 5 m above a flat surface. The rate of rotation increases very slowly until the cable snaps. the cable snaps when ac=20 m/s2. (x=0 at center of circle) a) how long does it take for the ball to hit the ground after the cable snaps? b) Relative to the position of the axle over the floor, what is the horizontal displacement of the ball( magnitude and direction)? c) What is the magnitude and direction of the velocity with which the ball hits the ground?
