Answer:
From Newton's second law of motion, acceleration can be calculated as follows:
F = ma
[tex]F(x) = (3+2x)i = m a\\a_x=\frac{3+2x}{m}[/tex]
Use the third equation of motion to find the velocity at position x
[tex]2as=v^2-u^2\\v=\sqrt{2a_xx+u^2}\\v=\sqrt{2\times \frac{3+2x}{m}\times x+0}\\v=\sqrt{\frac{6x+4x^2}{m}[/tex]
