Answer: OPTION A
Step-by-step explanation:
To find the zeros of the quadratic equation given in the exercise, you need to apply the proccedure shown below:
- You must rewrite it as following:
-You can apply the Quadratic formula, which is shown below:
In this case:
- Therefore, when you substitute values, you obtain:
The mass of the pendulum does not affect the period and frequency
The period can be determined using the formula:
T = 2π √(L/g)
where L is the length of the rope
and g is the acceleration due to gravity = 9.8 m/s2
Plugging in the values:
T = 2π √(5/9.8)
T = 10π/7 = 4.49 s
And for the frequency:
f = 1/T
f = 1/4.49
f = 0.22 Hz
Reduce the numbers with greatest common divisor 3
1/5 times 2
Calculate the product
2/5
