Kepler’s third law says that the orbital period (in years) is proportional to the square root of the cube of the mean distance (in au) from the sun (p ∝ a1.5). for mean distances from 0.1 to 32 au, calculate and plot a curve showing the expected keplerian period. for each planet in our solar system, look up the mean distance from the sun in au and the orbital period in years and overplot these data on the theoretical keplerian curve.

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts
