A motorcyclist is traveling east along a straight road. What is the velocity (in
meters per second) if it takes him 3 s to reach 60 meters? (Submit a number
response only!)

20m/s

Explanation:

velocity=displacement/time

velocity=60/3

velocity=20m/s

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.
