Question

A body of mass 8 kg is moved by a force F = 3x
N, where x is the distance covered. Initial position
is x = 2 m and the final position is x= 10 m. The
initial speed is 0.0 m/s. The final speed is​

Answer 1

The final speed is 6m/s.

Answer 2

Answer:

48 m/s

Explanation:

x=10-2=8m

So F=3×8=24 N

F=ma

Then a=3 m/s^2

Now ,

Final speed, v = 2×3×8

= 48 m/s
