Final answer:
The velocity at the end of 5 seconds is 27 m/s.
Step-by-step explanation:
To find the velocity at the end of 5 seconds, we need to use the formula:
Vf = Vi + at
Where Vf is the final velocity, Vi is the initial velocity, a is the acceleration, and t is the time.
In this case, the initial velocity (Vi) is 2 m/s, the time (t) is 5 seconds, and the acceleration (a) can be calculated using Newton's second law: F = ma. The force (F) is given as 10 N and the mass (m) is given as 2 kg.
So, a = F/m = 10 N / 2 kg = 5 m/s².
Plugging in the values into the formula, we get:
Vf = 2 m/s + (5 m/s²)(5 s) = 27 m/s.
Therefore, the velocity at the end of 5 seconds is 27 m/s.
