Welcome to the article A bomb is designed to explode 2 00 s after it is armed The bomb is launched from Earth and accelerated to an unknown final. On this page, you will learn the essential and logical steps to better understand the topic being discussed. We hope the information provided helps you gain valuable insights and is easy to follow. Let’s begin the discussion!
Answer :
To find the final speed of the bomb just before it explodes, we need the acceleration value, which is not provided in the question.
To find the final speed of the bomb just before it explodes, we can use the concept of acceleration. Let's assume the acceleration of the bomb is constant throughout its motion. The time it takes for the bomb to reach its final speed is given by the data given in the question:
- Time for explosion after arming = 2.9 s
- Time for explosion after launch = 2.0 s
The difference between these two times gives us the time it took for the bomb to reach its final speed:
Δt = 2.9 s - 2.0 s = 0.9 s
Now, using the equation:
v = u + at
where v is the final velocity, u is the initial velocity (assumed to be 0), a is the acceleration, and t is the time taken to reach the final velocity, we can solve for the final velocity:
v = 0 + a(0.9)
Since acceleration is constant, we can simplify the equation to:
v = 0.9a
From the given information, we know that the time it took for the bomb to reach its final speed is 0.9 seconds. Therefore, the final speed of the bomb is 0.9 times the acceleration.
So, the answer depends on the acceleration of the bomb, which is not provided in the question. If we have the value of acceleration, we can calculate the final speed.
