I have nearly completed this problem, but I am stuck on one of the final steps in my derivation. I would like to see a solution to compare with my own work
angle of contact of a particle is greater because for it's case the angle is equal to cos -1(2/3) which is less than that of sphere !!!... Because there is no (1/2 I w 2 )term involved in case of evaluating velocity term...
But in case of sphere it has that term so that the angle of contact of a sphere is greater than that of a particle!.

please help with problem 53 Rotational Motion Problem Solving "An expert is a person who has made all the mistakes that can be made in a very narrow field." -Niels Bohr 53. An inclined plane makes an angle of with the horizontal, as shown above. A solid sphere of radius R and mass M is initially at rest in the position shown, such that the lowest point of the sphere is a vertical height h above the base of the...
Bridging Problem: Oscillating and Rolling Two uniform, solid cylinders of radius R and total mass M are connected along their common axis by a short, light rod and rest on a horizontal tabletop (Figure 1). A frictionless ring at the rod's center is attached to a spring of force constant k, the spring's other end is fixed. The cylinders are pulled to the left a distance I, stretching the spring, then released from rest. Due to friction between the tabletop...
I need a step by step on 1 and 2 so I can teach myself. 1. A solid, uniform sphere with a mass of 2.0 kg is rolling from rest down an incline plane from the top of the plane. The incline plane makes an angle of 20° with the horizontal and has a height of 2.0 m. At the bottom of the incline plane, the surface levels out to a frictionless horizontal surface. A spring with a spring constant...
3. A very thin circular hoop of mass m and radius r is made to roll, without slipping, down a ramp with an angle of inclination (with respect to the horizontal), as shown in the figure below. See Figure 3. Note: The moment of inertia of the thin circular hoop is given by: I houp = mra Consider a system consisting of a ladder with a painter climbing said ladder. The ladder has a length 1 = 5,00 meters and...
Please i need these correct and ASAP . thanks Problem 11.49 Constants Pe Suppose a 5.5x1010 kg meteorite struck the Earth at the equator with a speed 2.5x104 m/s, as shown in (Figure 1) and remained stuck. Part A By what factor would this affect the rotational frequency of the Earth (1rev/day)? Express your answer using two significant figures. Figure < 1 of 1 ΟΙ ΑΣΦ ?

Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...
Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...
