I need help Bailey was driving her pickup truck carrying a load of feed and accelerated at 15 m/s² with a force of 375 N. She hits a pot hole and all of the feed falls out. Now the truck is half as massive as it was when loaded. If Bailey applies the same driving force of 375 N, what is the magnitude of the new acceleration? 375 m/s²
25 m/s²
750 m/s²
30 m/s²

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.
