Two identical capacitors store different amounts of energy: capacitor A stores 2.5 x 10-3 J, and capacitor B stores 2.8 x 10-4 J. The voltage across the plates of capacitor B is 11 V. Find the voltage across the plates of capacitor A.
A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 79.0 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.90 m/s2 until it reaches an altitude of 980 m. At that point its engines fail, and the...
