Mechanical energy is the answer
Answer:
The acceleration of the elevator machine is, a = 3 m/s²
Explanation:
Given data,
The mass on the one end, m = 5 kg
The mass on the other end, M = 10 kg
According to the Atwood's machine
Ma = Mg - T
ma = T - mg
Adding those equations,
a (M + m) = g ( M - m)
a = (M + m) / ( M - m)
Substituting the values,
a = (10 + 5) / (10 - 5)
= 3 m/s²
The acceleration of the elevator machine is, a = 3 m/s²
Answer:
L= 0.4 kgm²/s
Explanation:
The angular momentum of a hallow spinning sphere is
L = Iω
L = (0.02kgm²) × (20rad/s)
L= 0.4kgm²/s
