Question

What will be acceleration if a car changes its velocity from 10 m/s to 6 m/s in 2 seconds?

Answer 1

Answer:

given data:

u=10 m/s

v=6 m/s

t=2 s

to calculate:

acceleration,a=?

formula:

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

calculation:

$a = \frac{v - u}{t} \\ = \frac{6 - 10}{2} \\ = \frac{ - 4}{2} \\ = - 2$

here, negative sign represents decreasing acceleration.

your answer is -2

therefore, change in acceleration of car changing velocity of car from 10m/s to 6m/s in 2s is 2m/s²

hope it helps to you☺️
