Answer 2

Answer:

• 4 seconds.

Explanation:

We have,

• Initial velocity (u) = 2 m/s
• Final velocity (v) = 10 m/s
• Acceleration (a) = 2 m/s²

To find,

• Time taken (t)

Solution,

Acceleration = Change in velocity/Time

=> 2 = 10 - 2/t

=> 2 = 8/t

=> 2t = 8

=> t = 8/2

∴ t = 4 seconds

Verification:

> a = v - u/t

=> 2 = 10 - 2/4

=> 2 = 8/4

=> 2 = 2

∴ L.H.S = R.H.S
