Answer: Beth
Explanation: Dewayne (a) = 12/4 = 3m/s^2.
Beth (a) = 16/5 = 3.2 m/s^2.
So, Beth is the answer.
Answer: The acceleration of Beth is more than the acceleration of Dewayne.
Explanation:
Acceleration is defined as the rate of change of velocity with respect to time.
Mathematically,
[tex]a=\frac{v-u}{t}[/tex]
where,
v = final velocity
u = initial velocity
t = time taken
We are given:
[tex]v=12m/s\\u=0m/s\\t=4sec[/tex]
Putting values in above equation, we get:
[tex]a=\frac{12-0}{4}=3m/s^2[/tex]
Acceleration of Dewayne = [tex]3m/s^2[/tex]
We are given:
[tex]v=16m/s\\u=0m/s\\t=5sec[/tex]
Putting values in above equation, we get:
[tex]a=\frac{16-0}{5}=3.2m/s^2[/tex]
Acceleration of Beth = [tex]3.2m/s^2[/tex]
Hence, the acceleration of Beth is more than the acceleration of Dewayne.
