Find the inertia tensor for a uniform, thin hollow cone, such as an ice-cream cone, of mass M, height h, and base radius R, spinning about its pointed end.
A uniform rod of mass 4.2 kg and a length of 1.0 m is hinged to a wall at the left end and held in a horizontal position by a taut string. find the resulting angular acceleration of the rod
A 44-kg pole vaulter running at 11 m/s vaults over the bar. Her speed when she is above the bar is 1.0 m/s. determine her altitude as she crosses the bar
If a car takes a banked curve at less than a given speed, friction is needed to keep it from sliding toward the inside of the curve (a real problem on icy mountain roads).
q1. a 3.20 box that is several hundred meters above the surface of the earth is suspended from the end of a short
A toboggan approaches a snowy hill moving at 10.9 m/s. The coefficients of static and kinetic friction between the snow and the toboggan are 0.470 and 0.320, Find the acceleration of the toboggan as it is going up the hill
IF Earth's orbit were suddenly to become much more eccentric. keeping orbital semimajor axis as is, fixed at 1 AU, but let's imagine shifting both the Earth's perihelion and aphelion points by 0.9 AU, so that at perihelion we were only 0.1 AU from th..
An alpha particle (m = 6.7 x 10^-27kg, q = +3.2 x 10^-19C) has a speed of 30km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle throughout this motion. Find out the electric potential difference.
An object has a kinetic energy of 257J and a momentum of magnitude 21.8 kg·m/s. Find out the speed and the mass of the object.
A sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere.
A charge ?1.3 × 10^ ?5 C is ?xed on the x-axis at 9 m, Calculate the electric potential at the origin
A performer, seated on a trapeze, is swinging back and forth with a period of 9.95 s. what will be the new period of the system
