A person is going on a trail run was running for 90 minutes (assume 2 sig figs). If the runner was able to maintain an average pace of 6.0 mi/hr in the direction of increasing mile markers and they ended at mile marker 15.0, what mile marker did they start from?

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.
