Work is done in the course of exerting a Force through a Distance.
For a Force of 4.9 Newtons driven through a Distance of 0.650 Meter
write "4.9 Newtons Times 0.650 Meter Equals 3.185 "Newton-Dot-Meters".
Rewrite this last as 4.9 N × 0.650 m = 3.185 N•m.
The Newton-Dot-Meter is otherwise known as the "Joule" so the Work sought
is 3.185 Joules.
1 Joule is equal to 1/4.186 of a calorie or 1/4186 of a
kilocalorie so 3.185 Joules × 1/4186 kilocalorie per
Joule gives 3.185/4186 or 0.0007608695652 kilocalories.
