Answer:
a = 3.61[m/s^2]
Explanation:
To find this acceleration we must remember newton's second law which tells us that the total sum of forces is equal to the product of mass by acceleration.
In this case we have:
People are asleep at 3 am so energy would be less then.
A=m/s^2(meter per second square)
Work=joule
The answer is ...
28 km per hour
2. kinetic energy: due to it being transferred through collisions
