Physics: 8 word problems about velocity, distance, rotation, volume, time, speed

Until 1883, every city and town in the US kept its own local time. Today, travelers reset their watches only when the time change equals 1.0h. How far, on the average must you travel in degrees of longitude until your watch must be reset by 1.0h? (hint: Earth rotates 360 degrees in about 24 hours ) Gold, which has a mass of

A wave is generated and moves along a taut wire

See attached file. One end of a taut wire moved up and down with SHM generates a wave moving to the right along the wire. A 'primed' axis system, (x', y'), moving along with the wave, gives the x',y' coordinates of points on the wave as shown in ATTACHMENT #1. The wave's amplitude is ym', its velocity is v, and its wavelengt

Finding the ratio between two velocities down a ramp.

A marble and a cube are placed at the top of a ramp. Starting from rest at the same height, the marble rolls and the cube slides (no kinetic friction) down the ramp. Find the ratio of the center-of-mass speed of the cube to the center-of-mass speed of the marble at the bottom of the ramp.

A simple way to measure the speed of a bullet is with a ballistic pendulum. This consists of a wooden block mass, M, into which the bullet mass, m, is shot. The block is suspended from cables of length, l, and the impact of the bullet causes it to swing through a maximum angle, A. The initial speed of the bullet is v. a) How
