A spring with a force constant of 100.0 N/m is used to send a box sliding across a horizontal surface. The box, with a mass of 55.0 g, is pushed against the horizontal spring, compressing it 11.0 cm from equilibrium. The system is then released.
a) What is the speed of the box at the instant the spring is passing the point of being compressed 7.0 cm? [ it has now moved 4 cm away from the point of maximum compression ]
b) What is the maximum speed of the box and where does it occur?
c) The box loses contact with the spring at maximum speed. If an average force of friction of 1.0 N brings the books to a stop in 2.0 s, how far will the box have travelled after leaving the spring?
d) Draw an FBD representing the seciario and a diagram to present the situation.
A sound wave of velocity 330 m/s and wavelength 0.70 m is produced for 0.50 s. What is the frequency of the wave? How many complete waves are emitted in this time interval? After 0.50 s, how far is the front of the wave from the source of the sound?
A 40.0 kg wagon is towed up a hill inclined at 18.5o with respect to the horizontal. What is the acceleration of the wagon
a block of mass m1=8 rests on a frictionless surface and is attached to a light cord that is wrapped around a solid cylinder of mass m2, radius r=.130 m and moment of inertia I=1/2m2R^2.
Select two objects with flat surfaces such as books with different covers, for instance hard back and paperback. You will also need an inclined surface which can be tilted, such as a larger book or a small table.
In a Young's double-slit experiment, the seventh dark fringe is located 0.031 m to the side of the central bright fringe on a flat screen, which is 1.1 m away from the slits. The separation among the slits is 1.6 x 10 -4 m. What is the wavelength of..
