A body of mass 36 g moves with SHM of amplitude A = 13 cm and period T = 12 s. At time t=0 the displacement, x, is 13 cm. (a) Find the velocity when x = 5 cm. (b) Find the
force acting on the body when t = 2 s.

An artificial satellite circles the earth in a circular orbit at a location where the acceleration due to gravity is 6.03 m/s^2. determine the orbital period of the satellite.

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?

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.
