In this case the racket is the unbalanced force which acts upon the object in motion which is the birdie or however you call it
Into molecules of
sugar and
oxygen.
The complete reaction of the photosynthesis is in fact:
and the energy of the light coming from the sun is also used to make the reaction possible.
Assuming g = 10, the weight of the sled is 720N.
If it takes 26.5N to just pull the sled, then the frictional force f is 26.5N in the opposite direction.
f = μ*720N
26.5N = μ*720N
μ = 26.5N/720N = 0.037 (2 s.f.)
6480...i hope this is right im sorry if it’s not
