A 0.460-kg object attached to a spring with a force constant of 8.00 N/m vibrates in simple harmonic motion with an amplitude of 13.0cm. (Assume the position of the object is at the origin at t= 0.)
A mass m = 14 kg is pulled along a horizontal floor, with a coefficient of kinetic friction ?k = 0.09, for a distance d = 7.9 m. What is the work done by tension before the block gets to the incline
A glass camera lens, with an index of 1.55 is to be coatedwith a cryolite file (n~1.30) to decrease the reflection ofnormally incident green light (λo=500nm). What thickness should be deposited on the lens
A stone is dropped into a deep canyon and is heard tostrike the bottom 10.2 seconds after it is released. How deep is the canyon
A 8.0 kilogram object undergoes an acceleration of 2.7 m/s2. If this same force is applied to a 16.0 kg object, determine what acceleration is produced
A 6.0-kg object oscillates on a spring with a force constant of 160 N/m. The damping coefficient is 0.20 kg/s. If the driving frequency is varied, at what frequency will resonance occur
An electron is brought to a point 0.1 m from the center of the sphere. What is the force acting on the electron (magnitude and direction) ? What is the electric field (magnitude and direction ) at the point where the electron is located
A 20.0 kg floodlight in a park is supported at the end of a horizontal beam of mass 20.0 kg and length L that is hinged to a pole (beam and pole are perpendicular). A cable at an angle of 30.0 degrees with the beam helps to support the light. Find..
It is possible for a muon to be captured by a proton to form a muonic atom. A muon is identical to an electron except for its mass. Suppose some particle of mass 105.7 MeV/c2 is similarly captured to form an atom.
What minimum horsepower must a motor have to be capable to drag a 290 box along a level floor at a speed of 1.05 if the coefficient of friction is 0.50.
A 350 N beam of uniform density is hinged on a wall. A 200 N object hangs off the end of the beam at a distance l from the wall. A cable supports the beam by an upward tension of T at a distance of 2 l /3 from the wall and at an angle of 168 degrees..
A horizontal force of 100 N is applied to move a 45-kg cartacross a 9.0-m level surface. What work is done by the 100-N force
