Three people are playing tug-of-war. The figure below is the superman view of the problem.
a. If the total distance traveled by the center box was 5 m, how much work was done by each force?
b. What was the change in kinetic energy of the box?

design a transformer that will provide at the secondary 12v at 5 a when the primary is connected to 120 v 60 hz.
A 30uF capacitor initially charged to 30uC is discharged through a 2.9kohms resistor. How long does it take to reduce the capacitor's charge to 9.0uC
Determine the distance separating the red and violet light as it emerges from the glass. How does the angle of refraction into glass at the air-glass interface compare to the angle of incidence in glass at the glass-air interface?
A 12 kg object oscillates at the end of a vertical spring that has a spring constant of 1.70 x10^4 N/m. The effect of air resistance is represented by the damping coefficient b = 3N•s/m. Find the time interval that elapses while the energy of the ..
Calculate the number of coulombs of positive charge in 270 cm3 of (neutral) water. (Hint: A hydrogen atom contains one proton and an oxygen atom contains eight protons.) I keep getting 1.4E7 and its showing up wrong.
A fighter jet is launched from an aircraft carrier with the aid ofits own engines and a steam-powered catapult. The thrust of itsengines is 3.46 x 105 N. In being launched from rest itmoves through a distance of 69.6 m and has a kinetic energy of 6..
Provide the option of exploring the ray diagram that applies to this problem. The distance among an object and its image formed by a diverging lens is 8.00 cm. The focal length of the lens is -4.40 cm. Find (a) the image distance and (b) the object d..
