A 150 ice puch collides need on a smaller 100g ice puch, initially stationary, on a smooth, directionless surface. The initial speed of the 15pg puch is 3m/s .After the collision the 100g ice puch moves with a speed of 1.2m/s in the same direction. What is the final velocity of the 150 ice puch?

True or false graphs must include scales that increase by the same amount

Which of these has some mechanical energy? a. an atom b. heat inside earth c. a book on a shelf d. the fire from a lit match

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.
