. Add the following three force vectors, indicating your results by filling in the blanks for the x and y components for each, and expressing the resultant (the sum) in both rectangular and polar forms. Then write down the equilibrant for these two force vectors. Show your work here. These forces and angles are used in the lab report as well so keep a copy of your work.

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

heats surface water up

i think the answer would be reserve.
