In the forest (phrase—noun, but no subject and no verb) smashing against the bat (phrase—verb but no subject) before our first class (phrase) after the snowstorm (phrase) i am aware of the error (clause—subject and verb) when the saints go marching in (clause) between a rock and a hard place (phrase) broken shards of glass (phrase) because of her beautiful smile (phrase) because she smiled at him (clause)

Yes all those are correct, but I don't know what the question was

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

i don't know that i agree with that but what's the question ?
