Answer:
(a). The average acceleration during segment A is 2 m/s²
(b). The average acceleration during segment B is zero.
(c). The average acceleration during segment C is 4 m/s².
Explanation:
Given that,
A snowmobile moves according to the velocity-time graph ,
(a), We need to calculate the average acceleration during segment A
Using formula of average acceleration
[tex]a=\dfrac{v_{f}-v_{i}}{t_{2}-t_{1}}[/tex]
Where, [tex]v_{i}[/tex] = initial velocity
[tex]v_{f}[/tex] =final velocity
[tex]t_{i}[/tex] = initial time
[tex]t_{f}[/tex] =final time
Put the value into the formula
[tex]a=\dfrac{40-0}{20-0}[/tex]
[tex]a=2\ m/s^2[/tex]
(b). We need to calculate the average acceleration during segment B
Using formula of average acceleration
[tex]a=\dfrac{v_{f}-v_{i}}{t_{2}-t_{1}}[/tex]
Put the value into the formula
[tex]a=\dfrac{40-40}{50-20}[/tex]
[tex]a=0\ m/s^2[/tex]
(c). We need to calculate the average acceleration during segment C
Using formula of average acceleration
[tex]a=\dfrac{v_{f}-v_{i}}{t_{2}-t_{1}}[/tex]
Put the value into the formula
[tex]a=\dfrac{80-40}{60-50}[/tex]
[tex]a=4\ m/s^2[/tex]
Hence, (a). The average acceleration during segment A is 2 m/s²
(b). The average acceleration during segment B is zero.
(c). The average acceleration during segment C is 4 m/s².
