Question

A car started from rest and travels in uniform acceleration and its velocity becomes 40m/s in 10 seconds what is the acceleration of the car​

Answer 1

I'm not sure but I think it is 4m/s

Explanation:

As it was on rest so

initial velocity will be 0 so, u=0

velocity becomes 40m/s so, v=40

time is 10secs , t=10secs

formula is,

v= u+at

now by putting the concern values,

40= 0+a×10

40= 0+10a

now,

a= 40/10

a=4m/s

Answer 2

Answer:

________________________________________

★ Given

• initial velocity (u) = 0

• final velocity (v) = 40m\s

• Time (t) = 10 sec

★ To find

• acceleration = ?

★ Solution

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

$\implies$ a = $\dfrac{40 - 0}{10}$

$\implies$ a = $\dfrac{40}{10}$

$\implies$ a = 4 m\s²

Hence the acceleration is 4 m\s²
