The drawing shows a 26.1-kg crate that is initially at rest. note that the view is one looking down on the top of the crate. two forces, and , are applied to the crate, and it begins to move. the coefficient of kinetic friction between the crate and the floor is k = 0.347. determine the (a) magnitude and (b) direction (relative to the x axis) of the acceleration of the crate.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

another example of kinetic energy would be,

kinetic energy   >     moving energy
