Question

A car accelerates from rest to a speed of 30 m/s in 12 sec. Calculate the acceleration.​

Answer 1

Given :

• Initial velocity (u) = 0 m/s

• Final velocity (v) = 30 m/s

• Time interval (t) = 12 s

_____________________

To Find :

• Acceleration

_____________________

Solution :

Use 1st equation of motion :

⇒v = u + at

⇒30 = 0 + 12*a

⇒30 = 12a

⇒a = 30/12

⇒a = 2.5

➜ Acceleration is 2.5 m/s²

Answer 2

Answer:

hey mate here's ur answer

Explanation:

acceleration =2.5m/s²
