Answer:
15m/s
Explanation:
By using,
v = u + at
u = 0
a = 5m/s^2
At t = 3s
v = 5 × 3 m/s
v = 15m/s

Therefore the final velocity of the object after 3 seconds is 15 m/s.
Given:
The acceleration of an object = a = 5 m/s²
Time period = t = 3 s
Initial Velocity of the object = u = 0 m/s
To Find:
The final velocity ( v ) of the object after 3 s.
Solution:
The given question can be easily solved using the below-shown approach.
Given that,
The acceleration of an object = a = 5 m/s²
Time period = t = 3 s
Initial Velocity of the object = u = 0 m/s
Using the formula of kinematics,
⇒ v = u + at
Substituting the values of u, a, and t in the above equation.
⇒ v = 0 + ( 5 × 3 ) = 15
Therefore the final velocity of the object after 3 seconds is 15 m/s.
