Calculate the kinetic energy of a 90 kg skateboarder traveling at 10
meters/second down a ramp. (Plug the variables into the KE equation, and
solve!) *

A.450 Joules
B.900 Joules
C.1800 Joules
D.4500 Joules

would be false hope this out

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.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
