Question 10 (1 point)
A toy car is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.0 m/s2. What is the final velocity after 6.0 s? Vf = a*t + Vi
a
12 m/s
b
16 m/s
c
10.0 m/s
d
17 m/s

Answer 1

**For the first question:**

Acceleration is defined as:
**c. the rate of change of velocity.**

---

**For the second question:**

To find the final velocity (Vf) using the formula given:

\[
V_f = a \cdot t + V_i
\]

Where:
- \( a = 2.0 \, \text{m/s}^2 \) (acceleration)
- \( t = 6.0 \, \text{s} \) (time)
- \( V_i = 5.0 \, \text{m/s} \) (initial velocity)

Now plug in the values:

\[
V_f = (2.0 \, \text{m/s}^2) \cdot (6.0 \, \text{s}) + (5.0 \, \text{m/s})
\]

\[
V_f = 12.0 \, \text{m/s} + 5.0 \, \text{m/s}
\]

\[
V_f = 17.0 \, \text{m/s}
\]

So the final velocity after 6.0 s is:
**d. 17 m/s**.
