Before my mind wandered away from physics years ago, this always bugged me. Does anyone have any idea how a gyroscope placed inside a swinging pendulum would affect the pendulum's motion? (if we assume that the gyroscope spins freely and the pendulum, while dropped along a straight path, is free to swing in any direction)

A billiard ball of radius a is initially spinning about a horizontal axis with angular speed w_0 and with zero forward speed. If the coefficient of sliding friction between the ball and the billiard table is µ_k, find the distance the ball travels before slipping ceases to occur.

A small thin disk of radius r and mass m is attached rigidly to the face of a second thin disk of radius R and mass M as shown below. The center of the small disk is located at the edge of the large disk. The large disk is mounted at its center on a frictionless axle. The assembly is rotated through a small angle and released. Find the period of the motion.

Can you keep cutting space up into smaller and smaller 'parts' so to speak, does this go on forever?

i have been told that if one were to travel at the speed of light, one would age ( realitive to people not traveling at the speed of light ) much slower. in fact there is a popular anecdote explaining this, a twin brother gets on a space ship that travels at the speed of light , and upon returning moments later, his sister is an old woman.

ok, it defies all intuition about the nature of time to say that your physical movement through space effects the passing of time. if 3 seconds have passed, it shouldnt matter how fast you were traveling during that time, you still just 3 seconds older. but apperently i dont understand something. help me!

suppose that you are an accident investigator and you are asked to figure whether or not the car was speeding up before it crashed through the rail of the bridge and into the mudbank. the speed limit on the bridge is 24m/s. The deep is 4.9m, the distance traveled in the mudbank is 24m. it makes a right triangle with one side is 4.9m and the other side is 24m, hypotenuse is not given. WHat is your conclusion? explain!

By speeding up particles so fast that they approach the speed of light, then smashing them into blocks of lead, scientists have been able to create anti-matter. Can anybody describe the process (in lamen terms please) Of how exactly this happens?

Hi,

I have questions regarding these problems. I have tried to solve them without any success. If you’re adept in this area of physics, please try to provide some help.

1. The amusement park ride is the wave swings, or an upside down carousel wheel that spins people around. The period is 6 seconds; the radius is 10 m, and the angle of the chains while in motion is 60 degrees. The question: based on the angle, how much is the tension in each of the 4 chains holding you up? I am very bad at drawing vectors and making angles, and I got 200 N, which is most likely wrong.

These questions are in relation to a freefall ride, similar to the Tower of Terror at Disney World. You’re lifted up really high into the air for this elevator and dropped down several times. The total upward displacement is 62.484 m. This is the only information we’re provided.

2. What is your maximum velocity on the ride (occurs at 1/3 of the displacement)? I used the 4 kinematic equations, and I used the
