Some amusement parks have a ride where people are attached to a long cable, pulled back, and let go, like a pendulum. if the cable is 45.5 m long, what will the period of oscillation be?(unit=s)

The period is  

Explanation:

From the question we are told that

     The length of the cable is  

Let take acceleration due to gravity as

Now the period of the oscillation is mathematically represented as

substituting values

i'm thinking more like energy

a, c, d, e are all applying about success strategies.
