Question

•
An object starting from rest travels with an acceleration of
5 m/s2. What will be its velocity after 3 s?​

Answer 1

$heya...$

Here's ur answer...⬇⬇

⭐u = 0
⭐a = 5m/s^2
⭐v = ?
⭐t = 3sec

$a \: = \frac{v - u}{t}$

➡ 5 = v - 0 / 3
➡ v = 15m/s^2

Hope it helps you.....

Answer 2

GiveN :

• Initial velocity (u) = 0 m/s
• Acceleration (a) = 5 m/s²
• Time interval (t) = 3 s

To FinD :

• Final velocity

SolutioN :

Use 1st equation of motion :

⇒ v = u + at

⇒ v = 0 + 5 * 3

⇒ v = 0 + 15

⇒ v = 15

➜ Velocity after 3 seconds is 15 m/s
