What could be done to increase the acceleration of a dog sled? List two possibilities
1 answer:
To increase the acceleration of the dog sled, increase the applied force on the sled and reduce the mass on the sled.
According to Newton's second law of motion, the force applied to an object is directly proportional to product of mass and acceleration of the object.
F = ma
where;
<em>a </em><em>is the </em><em>acceleration </em><em>of the dog sled</em>
To increase the acceleration of the dog sled:
- Increase the applied force on the sled.
- Reduce the mass on the sled.

This is an incomplete question, here is a complete question.
The change in internal energy for the combustion of 1.0 mol of octane at a pressure of 1.0 atm is -5084.1 kJ. You may want to reference (Pages 381 - 385) Section 9.6 while completing this problem. If the change in enthalpy is -5074.2 kJ, how much work is done during the combustion? Express the work in kilojoules to three significant figures.
Answer : The work done during the combustion is, 9.9 kJ
Explanation :
Formula used :
where,
w = work done = ?
= change in enthalpy = -5074.2 kJ
= change in internal energy = -5084.1 kJ
R = gas constant = 8.314 J/mol.K
Now put all the given values in the above formula, we get:
Thus, the work done during the combustion is, 9.9 kJ
