The correct answer is
D.
unbalanced forces
In fact, according to Newton's second law, unbalanced forces acting on an object will accelerate the object:
where the term on the left is the resultant of the forces acting on the object, m is the object's mass, and a is its acceleration.
If there are unbalanced forces acting on the object, the acceleration of the object a is different from zero: this means that the object will change its speed or its direction, or it can also stop moving if the direction of the force is opposite to that of the motion.
Answer:
Walking burns up more energy,1740000J
Explanation:
Given that the displacement is 5.0km, and running at 10km/h and uses, walking at 3km/hr and uses 290watts:
Energy consumption for running is calculated as:
Energy consumption for walking is calculated as:
Walking is a slower process hence the need for more energy over longer periods raltive to running the same distance.
Hence walking burns more energy; 1,740,000J. It burns more because you walk for a greater period of time.
