Question

A car accelerates from 10 m/s to 22 m/s in 6 seconds. What is the car’s average acceleration?

-2 m/s2
12 m/s2
-12 m/s2
2 m/s2

Answer 1

Explanation:

`\underline{ \underline{ \text{Given}}} :`

• Initial velocity ( u ) = 10 m/s
• Final Velocity ( v ) = 22 m/s
• Time ( t ) = 6 seconds

`\underline{ \underline{ \text{To \: find}}} :`

• Acceleration of the car ( a )

`\underline{ \underline{ \text{Solution}}}:`

`\boxed{ \sf{a = (v - u)/(t)}}`

⇾
`\sf{a = (22 - 10)/(6)}`

⇾
`\sf{a = (12)/(6)}`

⇾
`\tt{a = 2 \: m {s}^( - 2)}`

`\red{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \tt{2 \: m \: / {s}^(2) }}}}}}`
