Answer:
Explanation:
KE = ½Iω²
ΚΕ = ½(mL²/3)ω²
ΚΕ = ½(0.63(0.82²)/3)4.2²
ΚΕ = 1.24541928
KE = 1.2 J

Answer:
a.) the speed at the bottom is greater for the steeperhill
Explanation:
since the energy at the bottom of the steeper hilis greater
As we can see from above that v is higher when h ishigher.
Answer: 2933 kg
Explanation:
Given
From the law of conservation of linear momentum, we know that
m(i)v(i) = m(f)v(f), where there is no external force acting on the system
m(i) = initial mass of the freight car system
m(f) = maximum mass of the freight car system
v(i) = initial linear velocity of the system
v(f) = final linear velocity of the system
2000 * 4.4 = m(f) * 3
3m(f) = 8800
m(f) = 8800 / 3
m(f) = 2933.3 kg
Therefore the maximum mass of grain that it can accept is 2933 kg
