Question

the velocity of a body increases from 2 m/s to 5 m/s in 6 seconds what is its acceleration ​

Answer 1

Answer:

0.5 m/s

Explanation:

=>Acceleration is rate of change in velocity.

a = (v - u )

t

• v = 5 m/s
• u = 2 m/s
• t = 6 seconds

=> ON PUTTING VALUES IN FORMUL

=> a = 5 - 2

6

=> a = 3/6 = 1/2 = 0.5 m/s^2

Answer 2

✰Question ✰

▪ The velocity of a body increases from 2 m/s to 5 m/s in 6 seconds what is its acceleration ?

✰Given:-

➧ Initial velocity of body (u) =2m/s.

➧ Final velocity of body (v) = 5m/s.

➧Time taken =6s

✰To Find :-

➧Acceleration (a) of body???

✰Solution :-

$acceleration = \frac{final \: velocity - \: initial \: velocity}{time \: taken} \\ \\ a = \frac{v - u}{t} \\ \\ a = \frac{5 -2}{6} \\ \\ a = \frac{3}{6} \\ a = 0.5ms {}^{ - 2}$

∴The acceleration of body 0.5m/s²

✰Additional information ✰

✸The Three equation of motions are

( 1)$v = u + at$

(2)$s = ut + \frac{1}{2} at {}^{2}$

(3)$v {}^{2} - u {}^{2} = 2as$
