Final answer:
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:
-
- Vf = 0 + 31m/s * 300s
-
- Vf = 9300m/s
Therefore, the final velocity of the object is 9300m/s.
