The kinetic energy (in joules) of a moving object can be calculated from the expression 1mv where m is the mass of the object in kilograms and v is its speed in meters per second. find the kinetic energy of a 0.145-kg baseball that is thrown at a speed of 40 meters per second.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
