The formula for kinetic energy is ...

                       K.E.  =  (1/2) (mass) (speed²) .

For the object in this question ...

                      K.E. = (1/2) (44 kg) (10 m/s)²

                              =        (22 kg) (100 m²/s²)

                              =         2,200  kg-m²/s²

                              =         2,200  Joules  . 

(That's the fourth choice on the list.)

Describe at least two ways that electromagnet force and weak nuclear forces are alike and two ways that they are different.
ruslelena [56]

Different: The weak nuclear force is responsible for radioactive decay within an atom of a substance, while the electromagnetic force causes electrostatic force between charged particles.


Different: The weak force has a very small range of effectiveness (where the force can be felt) while the electromagnetic force has an infinite range.


Same: Both forces act within an nucleus, or on a nuclear level.


Same: The weak nuclear force is mediated by charged particles called bosons, and the electrostatic force is only present within charged objects


The last one may be a bit of a stretch but I hope this helped a bit!
