Answer: 5 hours
Step-by-step explanation: first subtract 354.7 - 200.35 = 154.35
then divide 154.35 by 30.87 which is equal to 5

Answer:
The formula for the final velocity, bf in terms of initial velocity, v1, acceleration, a, and time is given as
Step-by-step explanation:
Given:
To Find:
bf = ?
Solution:
Acceleration:
Acceleration is defined as the ratio between the change in velocity of an object and the time it takes for the object to change the velocity.
In formula, this is written as:
Where,
'a' is the Acceleration.
'vf' is the final velocity
.
'vi' is the initial velocity.
't' is the time it takes for the object to accelerate from vf to vi
Here it is given as
So,
Where,
'a' is the Acceleration
'bf' is the final velocity
.
'v1' is the initial velocity.
't' is the time it takes for the object to accelerate from bf to v1.
On Solving the above equation 'bf' we get
....As required
Just plug in the square root of 100 in your calculator (10) and then either leave it as 10/49 or simplify it to a decimal...depending on what your teacher is expecting from you.
