A stretched string fixed at each end has a mass of 50 g and a length of 7.2 m. The tension in the string is 47 N. What is the vibration frequency for this harmonic?
A ball with an intial velocity of 8.00 m/s rolls up a hill without slipping. Treating the ball as a spherical shell, calculate the vertical height it reaches
The kinematics and dynamics of rotation around a fixed axis of a rigid body are mathematically much simpler than those for free rotation of a rigid body; they are entirely analogous to those of linear motion along a single fixed direction, which is n..
A truck is carrying a steel beam of length16.0m on a freeway. An accident causes the beam to be dumped off the truck and slide horizontally along the ground at a speed of22.0m/s. The velocity of the center of mass of the beam is northward while th..
An artificial satellite circles the Earth in a circular orbit at a location where the acceleration due to gravity is 6.83 m/s2. Determine the orbital period of the satellite
A sample is bombarded by incident X-rays, and free electrons in the sample scatter some of the X-rays at an angle of -0= 122.0 degrees, Determine the wavelength (in nm) of the incident X-rays
A projectile, fired by unknown initial velocity, lands 22.0 s later on the side of a hill, 3250 m away horizontally and 425 m vertically above its starting point. (Ignore any effects due to air resistance.) What was its maximum height above its launc..
Four 1.2 kg masses are located at thec orners of a square 0.80 m on eachside. Find the magnitude and direction of the gravitational forceon a fifth 1.2 kg mass placed at the midpoint of the bottom side of the square.
A car is hauling a 92 kilogram trailer, to which it is connected by a spring. The spring constant is 2300 N/m. Calculate how much the spring stretches
A rifle with a barrel length of 57cm fires a 12g bullet with a horizontal speed of 450m/s, What resistive force (assumed to be constant) does the wood exert on the bullet
A uniform spherical shell of mass M = 13.0 kg and radius R = 0.390 m can rotate about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 0.200 ..
two hockey players strike a puck of mass of .164kg, one from westward force of 1.10 x 10^3 Newtons, what is the degrees north of west
