Explanation of Solution
Given information:
The final velocity
The initial velocity,
The acceleration rate,
The time,
The formula for acceleration:
Calculation:
The given formula for acceleration is,
Multiply the term t on each side of the above formula.
Add the term
This is the formula of final velocity.
Substitute 4 for
Hence, the required final velocity is 10 feet per second.
