Answer:
A=0.199
Explanation:
We are given that
Mass of spring=m=450 g=
Where 1 kg=1000 g
Frequency of oscillation=
Total energy of the oscillation=0.51 J
We have to find the amplitude of oscillations.
Energy of oscillator=
Where
=Angular frequency
A=Amplitude

Using the formula



Hence, the amplitude of oscillation=A=0.199
Answer:

Explanation: plato
Answer:
5.7 s
Explanation:
Given:
a = 3.0 m/s²
v₀ = 8.0 m/s
v = 25.0 m/s
Find: t
v = at + v₀
25.0 m/s = (3.0 m/s²) t + 8.0 m/s
t ≈ 5.7 s
I don't understand what u wanna ask pls make it clear!
