Question

Imagine a car moving at a speed of 10 m/s it starts speeding up at an acceleration of 2 m/s/s. What will the car's speed be after 2, 4, and 6 seconds?

Answer 1

Answer:

14 m/s

18 m/s

22 m/s

Explanation:

The car is moving at constant acceleration, so we can find its velocity at time t using the equation:

$v=u+at$

where

u = 10 m/s is the initial velocity

$a=2 m/s^2$ is the  acceleration

t is the time

Substituting the different times, we find:

At t = 2 s:

$v=10+(2)(2)=14 m/s$

At t = 4 s:

$v=10+2(4)=18 m/s$

At t = 6 s:

$v=10+2(6)=22 m/s$
