Question

What is the final velocity of an object that accelerates from rest at 31m/s for 300s?

Answer 1

The final velocity of an object that accelerates from rest at 31m/s for 300s is 9300m/s.

Step-by-step explanation:

The final velocity of an object that accelerates from rest at 31m/s for 300s can be calculated using the equation:

Vf = Vo + at

Where:

• 
  
• Vf is the final velocity
• 
  
• Vo is the initial velocity (which is 0 in this case, since the object starts from rest)
• 
  
• a is the acceleration
• 
  
• t is the time

Plugging in the values:

• 
  
• Vo = 0
• 
  
• a = 31m/s
• 
  
• t = 300s

We can calculate:

1. 
   
3. Vf = 0 + 31m/s * 300s
4. 
   
6. Vf = 9300m/s

Therefore, the final velocity of the object is 9300m/s.
