Two identical discs are spinning on a vertical rod, at different rotation rates. The bottom disc is or a support, and the top disc is sliding down to hit the bottom one. Once they hit, they rotate together as a single object. Calculate the rotation rate just after the collision, in rev/s. Bottom rotation rate: 4700 rev/s Top rotation rate: 8500 rev/s • Mass 280 grams Radius 28 cm

Hello, I need help with physics. Thank you!Consider a circle-circle collision, where both circles are identical and are able to move. The coefficient of resititution is 0.842. Ball A has an initial velocity of (0.08, 6.54) px/s and is centred at pixel position (4.02, -7.56) at the moment of impact. Ball B is stationary and is centred at pixel position (0.9, -0.71) at the moment of impact. Calculate the magnitude of the change in velocity along the normal for ball A or B (ignoring friction). Note that this is just a number, not a vector. Leave your answer accurate to 2 decimal places.
Hi I am in physics I. Here is the description. A sphere has a mass of 8200 kg and a radius of 90 cm and floats with nearly zero friction on a thin layer of pressurized water. Suppose that she pushes on the sphere tangent to its surface with a steady force of F = 70 N and that the pressured water provides a frictionless support. How long will it take her to rotate the sphere one time, starting from rest? Please include details step by step. Thank you!
Thank you in advance for your quick help. On your vacation, you visited several casinos in Las Vegas, and in one of them, you stopped by a roulette table. You observed that roulette wheel takes about 30 seconds to come to a stop, and it completed 25 revolutions in this time. How fast was it rotating at the very beginning before starting to slow down?
A concrete mixer truck (see below) has a large drum on the back that rotates in order to agitate concrete (so the concrete doesn't solidify during transport). The drum has a diameter of about 2.2 meters. When operating at its normal operational speed, the drum goes through a complete rotation every 3.7 seconds. (1) Find the angular speed of rotating drum in radians per second. (2) Find the centripetal acceleration of a point on the surface of the drum. (3) If we can approximate the drum as a solid cylinder of mass 23,100kg, how much rotational kinetic energy does the drum have when it is rotating at its normal operational speed? The moment of inertia for a solid cylinder is Isolid cylinder=1/2MR2
Global warming is a cause for concern because even small changes in the Earth’s temperature can have significant consequences. For example, if the Earth’s polar ice caps were to melt entirely, the resulting additional water in the oceans would flood many coastal areas. Model the polar ice as havingmass 2.30 × 1019 kg and forming two flat disks of radius 6.00 × 105 m. Assume the water spreads into an unbroken thin, spherical shell after it melts. Calculate the resulting change in the duration of one day both in seconds and as a percentage.
When a roulette wheel is set spinning and then released, it eventually slows down to a stop. Explain, why the wheel doesn't simply keep spinning forever.
Describe how to change from degrees to radians, and from radians to revolutions. A motorcycle engine revs up from 2000 to 11,000 rpm in 6 seconds. How many revolutions does it go through in that time? Show, or describe, the steps you take to get your answer.
At 714 A.M. on June 30, 1908, a huge explosion occurred above remote central Siberia, at latitude 61 N and longitude 102 E; the fireball thus created was the brightest flash seen by anyone before nuclear weapons. The Tunguska Event, which according to one chance witness “covered an enormous part of the sky,” was probably the explosion of a stony asteroid about 140 m wide. (a) Considering only Earth’s rotation, determine how much later the asteroid would have had to arrive to put the explosion above Helsinki at longitude 25 E. This would have obliterated the city. (b) If the asteroid had, instead, been a metallic asteroid, it could have reached Earth’s surface. How much later would such an asteroid have had to arrive to put the impact in the Atlantic Ocean at longitude 20 W? (The resulting tsunamis would have wiped out coastal civilization on both sides of the Atlantic.)
A record player disk base with a mass of 420 g rotates freely at an angular speed of 33 1/3 rpm. A 25 g mouse is initially riding on the rim of the disk, 15 cm from the center. If the mouse walks to the center of the disk, will the disk rotate faster, slower, or at the same rate? Explain. Calculate the angular speed of the disk when the mouse reaches the center.
Ballistic pendulum: A projectile of mass m = 1 kg is fired with an initial speed v0 = 20 m/s at the bob of a pendulum with radius R = 3 m. The bob has mass M = 4 kg and is suspended by a rod of negligible mass. After the collision the projectile and bob stick together and swing at speed vf through an arc reaching height h and stop. (assume g=10 m/s2) (3) What is the centripetal acceleration of the pendulum just after the collision ?
Competitive divers pull their limbs in and curl up their bodies when they do flips. Just before entering the water, they fully extend their limbs to enter straight down. Explain the effect of both actions on their angular velocities. Also explain the effect on their angular momenta.
Integrated Concepts Riders in an amusement park ride shaped like a Viking ship hung from a large pivot are rotated back and forth like a rigid pendulum. Sometime near the middle of the ride, the ship is momentarily motionless at the top of its circular arc. The ship then swings down under the influence of gravity. (a) Assuming negligible friction, find the speed of the riders at the bottom of its arc, given the system's center of mass travels in an arc having a radius of 14.0 m and the riders are near the center of mass. (b) What is the centripetal acceleration at the bottom of the arc? (c) Draw a free body diagram of the forces acting on a rider at the bottom of the arc. (d) Find the force exerted by the ride on a 60.0 kg rider and compare it to her weight. (e) Discuss whether the answer seems reasonable.
