Here are the answers to your quiz questions:

**Question 1:**
To find the final velocity \( v \) of the bike, use the formula:

\[ v = u + at \]

Where:
- \( u \) = initial velocity = 25 m/s
- \( a \) = acceleration = 0.5 m/s²
- \( t \) = time = 20 seconds

Plugging in the values:

\[ v = 25\, \text{m/s} + (0.5\, \text{m/s}^2 \times 20\, \text{s}) \]
\[ v = 25\, \text{m/s} + 10\, \text{m/s} \]
\[ v = 35\, \text{m/s} \]

**Answer: 35 m/s**
