the free-body diagram below shows the forces acting on a bicycle as the
rider pedals to the right. the vectors are not drawn to scale. the bicycle has a
weight of 1000 n and a pedaling force of 400 n. as it moves, it encounters
300 n of air resistance. what is the net force acting on the bicycle in the x-
direction?
air resistance
pedaling force

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.
