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
The potential energy is 490 because
1•9.8•50=490 hope it helps!
Answer:
20.2
Explanation: Divide 726/34 and you get 20.16 round it and you get 20.2
(a.) The acceleration of the car can be calculated using the equation,
2ad = v²
Substituting,
2(a)(180 m) = (22.2 m/s)²
From the equation above, we achieve the value of a = 1.369 m/s²
(b) The force necessary is calculated below,
F = (1,300 kg)(1.369 m/s²)
F = 1,779.7 N
(c) Coefficient of friction,
1,779.7 N = (1,300)(9.81)(x)
The value of x from the generated equation,
x = 0.14.
