F=m*a=>a=F/m=10000/1267=7.89 m/s²
d=v₀t+a't²/2<=>394.6=112.5*a'=>a'=3.5
a-a'=7.89-3.5=4.39 m/s²
This difference causes friction forces
We apply the second principle of dynamics: vector: F + N + G + Ff = ma (vector vectors, I can not here)
Scalar: Ox: F-Ff = ma
Oy N-mg = 0
Ff = -ma+ F =-1267*7.89+10000=-8869+10000=1131 N
This frictional force (Ff) is opposite to the traction (F)
Answer:
Density is determined by an object's mass and volume.
Explanation:
If two objects take up the same volume, but one has more mass, then it also has a higher density.
Answer:
Biomedical engineering
Explanation:
this is because plant sees are important
The "i" component of a vector is in the x-direction. Therefore, the x-component is 3 m/s.
Answer:
Deceleration
Explanation:
The amount by which a speed or velocity decreases
