What constant acceleration is required to increase the speed of a car from 30 mi/h to 52 mi/h in 5 seconds? (Round your answer t

Alenkasestr [34]

Answer:

$a = 9.84 m/s^2$

Step-by-step explanation:

Given:

Initial speed (Vi) = 30 mi/h = 67.1 m/s

Final speed (Vf) = 52 mi/h = 116.32

Time period(t) = 5 seconds

We know the formula of acceleration in terms of initial speed, final speed and time:

$a = \frac{Vf -Vi}{t}$

$a = \frac{116.32-67.10}{5}$

$a = 9.84 m/s^2$
