Question

a parked car starts to move and reaches a velocity of 75 m/s in 10 seconds. the initial velocity of the car is 0 m/s and its final velocity is 75 m/s. acceleration = (final velocity - initial velocity) / time interval

Explanation:

Step1: Identify values

Initial velocity $u = 0$ m/s, final velocity $v=75$ m/s, time $t = 10$ s.

Step2: Apply acceleration formula

$a=\frac{v - u}{t}=\frac{75 - 0}{10}$

Step3: Calculate acceleration

$a=\frac{75}{10}=7.5$ m/s²

Answer:

$7.5$ m/s²
