Answer:
The elastic potential is 1/2 as much.
Explanation:
The reason I say this is because of you take a new rubber band, after stretching the first time, all the way until it doesn't snap, you stretch it again and there's not as much resistance as when it was new.
I hope this helps.
Answer:
A) Walking would burn up more energy
B) Walking: 1,914,000 J
Running: 1,386,000 J
C) Even though running is more intense and burns energy at higher rate, it burns energy for a much shorter time than walking.
Explanation:
Watt is a unit for power that is equivalent to Joules per second (J/s). Therefore, to figure out the energy burnt up during an activity, first we need to know how long (in seconds) that activity took.
1- Running
V = 10.0 km/h
d = 5.50 km
t = 5.50/10 = 0.55 h = 0.55(h) *60 (min/h) *60(s/min) = 1,980 s
2- Walking
V = 3.0 km/h
d = 5.50 km
t = 5.50/ = 1.83333 h = 1.83333(h) *60 (min/h) *60(s/min) = 6,600 s

Running: 1,386,000 J
