The last stage of a rocket is traveling at speed of 7800 m/s. This last stage is made up of two parts that are clamped together, namely, a rocket case with mass of300.0 kg and payload capsule by a mass of 220.0 kg. When the clamp is released, a compressed spring causes the two parts to separate with a relative speed of920.0 m/s. suppose that all velocities are along the similar line.
A) What is the speed of the case after they separate?
B) What is the increase in kinetic energy after they separate?
C) What is the speed of the payload after they separate?
D) What is the total kinetic energy of the two parts before they separate?
A 2.5 kg piece of the same metal, intitally at a temperature of 190°C is dropped into the water. If the water temperature rises from 16.0°C to 17.8°C, calculate the specific heat of the metal.
