OH
I didn't even think about that... wow I'm really dropping the ball tonight.
So:
I = .5mr^2
F = Ia/r
f = .5mr^2a/r = .5mra
= (6000)(.9)(-81.125)/2
= -219037.5 N
to find α, could I not do this?:
wf = wi + αt
wf = 0, so
-wi = αt
(where wi = 62 rpm/60 sec * 2π rad = 6.49 rad/s)
so
- 6.49 = α(.08)
α = -81.125 rad/s2

a)-The massive grinder for wood-pulp in a newsprint paper factory, which can render about a half Tonne of wood into a thin soup in less than a minute, is essentially a stone cylinder of radius 0.900 m and mass about 6.00 Tonnes. An enormous motor spins this cylinder on its...
Okay, so:
Distance from Earth to corresponding planet:
Venus = 1.500×108 km - 1.080×108 km = 42,000,000 km = 4.2E10 m
Jupiter = 7.780×108 km - 1.500×108 km = 628,000,000 km = 6.28E11 m
Saturn = 1.430×109 km - 1.500×108 km = 1,280,000,000 km = 1.28E12 m
F = GME[(.888ME/(4.2E102) +...

Calculate the total force on the Earth due to Venus, Jupiter and Saturn, assuming all four planets are in a line (see figure).
An amateur astronomer measures the masses to be MV = 0.888 ME, MJ = 324 ME, MS = 98.0 ME, and their distances from the Sun are 1.080×10^8 km...
Homework Statement
If one micrometeorite (a sphere with a diameter of 1.50×10-6 m) strikes each square meter of the surface of the Moon each second (1 micrometeorite/m2/s), how many years will it take to cover the Moon to a depth of 1.80 m?
Assume that after impact, the micrometeorites...
