Ropes utilized in rock climbing are "springy" so they cushion a climber's fall. A particular rope has a force law given by F=-kx +bx^2, where k=223 N/m, b=4.1 N/m^2 and x is the amount of stretch? Discover the potential energy stored in this rope when it's been stretched 2.62m, taking U=0 at x=0.
suppose that electrical attraction rather than gravity were responsible for holding the moon in orbit around the earth.
two 4.0 cm times 4.0 cm electrodes spaced 2.0 mm apart form a parallel-plate capacitor. inside the capacitor the
A physical pendulum consists of a meter stick (of mass 0.3 kg) that is pivoted at a small hole drilled through the stick a distance x from the 50 cm mark. The meter stick is then released from rest (at a small angle from vertical) and allowed to o..

In a popular amusement park ride, a rotating cylinder of radius3.00 m is set in rotation at anangular speed of 6.00 rad/s, as inFigure P7.51. The floor then drops away, leaving the riderssuspended against the wall in a vertical position. What mini..
A rubber ball is bouncing along the lever floor. after each bounce it only goes back up to half of the height that it just fell from. make a proportional sketch displaying this ball bouncing six times.
A small glass bead has been charged to +30.0nC. What is the charge on the ball bearing
Water flowing out of a horizontal pipe emerges through a nozzle is 0.48 cm. The speed of the water in the pipe is 0.62 m/s. Treat the water as an ideal fluid, and determine the absolute pressure of the water in the pipe.
An electron is moving north in a region where the magnetic field is south. What is the magnetic force exterted on the electron
In a tug of war on a slippery floor, Jose of mass M pulls on the rope and imparts an acceleration a to Juanita, of mass m. Calculate the tension if Jose's mass is 80kg and Juanita's mass is 60kg, and she accelerates toward Jose at .1m/s2
