Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Hi

Here is the equation for the momentum

                                              p = m x v

here m indicates mass and v indicates velocity.

Using words it can also be written as:

                                  Momentum = mass x velocity

Momentum of a body is basically the product of its mass and velocity.The standard unit of momentum is the kg x m/s, because the unit of mass is kilograms or kg and unit of veocity is metre per second or m/s, Therefore the product of both is the unit of momentum.

Hope it help!

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
