A 0.401 kg bead can slide on a curved wire.
Assume h1= 4.03 m and h2= 1.64m. If the wire is frictionless and the bead is released with an initial speed of 12.8 m/s in the forward direction then find the speed of the bead at B.
If the wire is frictionless, find the speed at c.
At time t = 0 s, apple 1 is dropped from a bridge onto a roadway beneath the bridge; somewhat later, apple 2 is thrown down from the same height.
For a damped oscillator with a mass of 350 g, a spring constant 59.00 N/m and a damping coefficient of 89 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 30 cycles.
A tuning fork of unknown frequency is noted to be higher than one marked 512 hz and lower than one marked 1000 hz. You discover resonance points at .11 m and .53 m. Using 347 m/s for speed of sound what is the frequency of the new fork.
A proton is travelling to the right at. It has a head-on perfectly elastic collision with a carbon atom. The mass of the carbon atom is 12 times the mass of the proton. What are the speeds of each after the collision? What is the direction of the pro..
A house has a floor area of 113 m2 and an outside wall that has an area of 26 m2. The earth's magnetic field here has a horizontal component of 3.0 multiplied by 10-5 T that points due north and the vertical component of 4.9 multiplied by 10-5 T p..
