Answer:
0.2289
Explanation:
Power required to climb= Fv where F is force and v is soeed. We know that F= mg hence Power, P= mgv and substituting 700 kg for m, 9.81 for g and 2.5 m/s for v then
P= 700*9.81*2.5=17167.5 W= 17.1675 kW
To express it as a fraction of 75 kw then 17.1675/75=0.2289 or 22.89%
Answer:
force is the answer because force is pushing the item
Models show how the atoms in a compound are connected.
KE = 1/2mv^2
KE = 1/2 (5kg)(3m/s)
KE = 22.5 J
That's the "Atomic Mass" of the atom.
