Question

How much time does it take for a car to accelerate from 3.44 m/s to 20.9 m/s if the average acceleration is 6.00 m/s^3

Answer 1

Answer:

The time is 2.91 s.

Explanation:

Given that,

Initial velocity = 3.44 m/s

Final velocity = 20.9 m/s

Acceleration = 6.00 m/s²

We need to calculate the time

Using equation of motion

$v = u+at$

$t=\dfrac{v-u}{a}$

Where, u = initial velocity

v = final velocity

a = acceleration

Put the value in the equation

$t =\dfrac{20.9-3.44}{6.00}$

$t=2.91\ s$

Hence, The time is 2.91 s.
