Question

Using the graph, calculate the car's acceleration.

A) 0.12 m/
`s^(2)`
B) 0.13 m/
`s^(2)`
C) 7.5 m/
`s^(2)`
D) 8.3 m/
`s^(2)`

Answer 1

Option C.
`7.5(m)/(s^(2))`

Explanation:

we know that

The car's acceleration is equal to the difference between the initial and final velocities, divided by the time

In this problem

Let

`A(0,0), B(6,45)`

therefore

`a=(45-0)/(6-0)=7.5(m)/(s^(2))`
