Answer:
Explanation:
The gravitational force between two objects is given by
where
G is the gravitational constant
m1, m2 are the two masses
r is the separation between the two masses
In this problem, we have
the mass of each truck
r = 2.0 m is their separation
Substituting,
Answer:
- 273.77 rad/s^2
Explanation:
fo = 3800 rev/min = 3800 / 60 rps = 63.33 rps
f = 0
ωo = 2 π fo = 2 x 3.14 x 63.33 = 397.71 rad/s
ω = 2 π f = 0
θ = 46 revolutions = 46 x 2π radian = 288.88 radian
Let α be the angular acceleration of the centrifuge
Use third equation of motion for rotational motion
α = - 273.77 rad/s^2
