Question

6 a tesla is moving at + 8 m/s when the driver steps on the accelerator pedal and accelerates for 4 seconds until they reach + 36 m/s. what is the acceleration of the tesla? a +28 m/s² b +11 m/s² c +24 m/s² d +7 m/s²

Explanation:

Step1: Recall the acceleration formula

The formula for acceleration \( a \) is \( a=\frac{v_f - v_i}{t} \), where \( v_f \) is the final velocity, \( v_i \) is the initial velocity, and \( t \) is the time.

Step2: Identify the given values

We have \( v_i = +8\ m/s \), \( v_f = +36\ m/s \), and \( t = 4\ s \).

Step3: Substitute values into the formula

Substitute the values into the formula: \( a=\frac{36 - 8}{4} \).
First, calculate the numerator: \( 36 - 8 = 28 \).
Then, divide by the time: \( a=\frac{28}{4}=7\ m/s^2 \).

Answer:

D. +7 m/s²
