A spacecraft of mass 20000 kg is travelling at 1500 m per second. It's rocket ejects hot gas at a speed of 1200 m per second relative to the spacecraft. during one burn the rockets are fired for a period of five seconds. in this time the speed of the spacecraft's increases by 3 m per second. what is the acceleration of the spacecraft? assuming that the mass of the fuel injected is negligible compared with the mass of spacecraft determine the distance traveled during the burn. what is the thrust produced by The Rockets? determine the mass of the gas ejected by the rocket during the burn.

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
