Luca Congi, of the 2007 Grey Cup Champions Saskatchewan Roughriders, kicks the football with an initial speed of 20 m/s 45.0° above the ground. D. J. Flick, standing on the goal line 60.0 meters away in the direction of the kick, starts running to meet the ball the instant it is kicked.. Neglecting air resistance, what must be his average speed in order to catch the ball just before it hits the ground?

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.
