Question

a) The velocity of an object changes from 6 m/s to 18 mus in 6 seconds. What is its
acceleration?

Answer 1

Answer:

this is a answer

Explanation:

this is a answer

Answer 2

Given:-

・Initial velocity = 6 m/s

・Final Velocity = 18 m/s

・Time taken = 6 seconds

To Find:-

・Accelaration

By Using 1st Kinematical equation :-

$\longrightarrow \large \underline{ \boxed{ \sf v = u + at}} \bigstar$

Where, v, u, a and t represents final velocity, initial velocity, Accelaration and time taken respectively.

↝ v = u + at

↝ 18 = 6 + 6 × a

↝ 18 - 6 = 6a

↝ 12 = 6a

↝ a = 12/6

↝ a = 2 m/s²

hence, the required Accelaration is 2m/s²

2nd Kinematical equation :-

$\\ \rightarrow \underline{ \boxed{ \sf{s = ut + \dfrac{1}{2}a {t}^{2} }}} \bigstar$

Where, S, u, t and a represents Displacement, Initial velocity, time taken and Accelaration.

3rd Kinematical equation :-

$\\ \rightarrow \underline{ \boxed{ \sf {v}^{2} - {u}^{2} = 2as }} \bigstar$

Where, v, u, a and s represents Final velocity, initial velocity, Accelaration and displacement
