A car with a mass of 2000 kg accelerates at 6 m/s'at a green light. What is the car's force?​

Car's force is 12000 N.

Explanation:

→ Force = Mass × Acceleration

→ Force = 2000 kg × 6 m/s²

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.
