A38-kilogram canoe broke free of its dock and is now floating downriver at a speed of 2.2m/s. what is the canoe's momentum? show your work.

The momentum of an object is given by:

where m is the object's mass and v its velocity.

In this problem, the mass of the canoe is m=38 kg, while its velocity is v=2.2 m/s. Therefore, if we substitute these numbers into the equation, we find the momentum of the canoe:

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )
