Question

the speed of a car changes from 12m/s to 24m/s in 1 minute magnitude of aclerataion is what​

Answer 1

Explanation :

Given :

• Initial speed = 12 m/s
• Final speed = 24 m/s
• Time = 1 minute

To find :

• Magnitude of acceleration

Here,

□ Initial speed (u) = 12 m/s

□ Final speed (v) = 24 m/s

□ Time (t) = 1 minute

= (1 × 60) s

= 60 s

What is acceleration?

Acceleration is defined as rate of change in speed / velocity.

Now we will use 1st equation of motion :

⇒ v = u + at

Substituting values,

⇒ 24 = 12 + a × 60

⇒ 24 = 12 + 60a

⇒ 24 - 12 = 60a

⇒ 12 = 60a

⇒ a = 12/60

⇒ a = 0.2 m/s²

∴ Magnitude of acceleration = 0.2 ms-²
