Answer:
Newton's second law: F=ma.
Force = mass x acceleration
This basically means, that the more massive something is, and the faster it is going, the more force the object will have.
So, the factors that can be used to find acceleration are:
F=ma
a=F/m
So, we see that the correct answer is A, mass and force.

There is nothing to choose from
Answer:
a)ω₂=127.64 rad/s ( min)
ω₁= 333.32 rad/s ( max)
b) At d₂= 11.75 cm ,ω₂=127.64 rad/s
d₁=4.5 cm,ω₁= 333.32 rad/s
c)α = 7.1 x 10⁻³ rad/s²
Explanation:
Given that
r₂= 11.75 cm
r₁=4.5 cm
v= 7.5 m/s
a)
We know that
v=ω r
ω =Angular speed
r= radius
v= velocity
When d₂= 11.75 cm :
v=ω r
7.5 x 2 =ω₂ x 0.1175
ω₂=127.64 rad/s ( min)
N₂=1219.4 rpm
When d₁=4.5 cm :
v=ω r
7.5 x 2=ω₁ x 0.045
ω₁= 333.32 rad/s ( max)
N₁=3184.58 rpm
The average angular acceleration α given as
ω₁ = ω₂ + α t
333.32 = 127.64 + α x 8 x 60 x 60
α = 7.1 x 10⁻³ rad/s²
