Answer:
The velocity is given as -B sin(ωt) while the acceleration is given as -C cos(ωt).
Explanation:
As the complete question is not given here, a search for the question is made and the complete question is as given in the attached image.
From the given data the equation of displacement x as it varies with time is given as
Here
- A is the distance of the point at which it is released from the equilibrium position
- ω is the characteristic of the system measured in rad/sec.
Now in order to find the velocity, it is given as
Suppose that
So the equation becomes
So the velocity is given as -B sin(ωt).
Now the acceleration is given as
Suppose that
So the equation becomes
the acceleration is given as -C cos(ωt).

Explanation:
On the 15th of April, 1980, our boat left the Mariel harbour. Our destination? The United States. I was what people referred to as a 'Marielito'; Meaning, a refugee from Cuba. You may be wondering why I left Cuba in a crowded boat alongside many others. I will explain.
The Cuban economy had just taken a downturn in 1980 and there were job shortages and housing problems. Fidel Castro was president at the time. Some Cubans broke into the Peruvian Embassy to seek asylum due to the hardship. I couldn't stand to survive the hardship the economic downturn brought. So, when the Castro regime announced in April that all Cubans who wished to leave to the United States were free to go, I chose to leave. I had a sister who had moved and settled in Florida earlier. She arranged for me to come to her.
I boarded a small boat at the port of Mariel in Havana and arrived Florida the next day.
