Dear student,
If we assume that the force acting on the particle is constant, then we can find the amount of force as:
F=\frac{P}{v}=\frac{2}{1}=2 N
The acceleration of the particle would be given by:
a=\frac{2}{\frac{10}{7}}=\frac{7}{5} m/s^{2}
Hence,the velocity would be given by:
v^{2}=u^{2}+2as=1^{2}+2\times \frac{7}{5}\times 10=1+28=29 \Rightarrow v=\sqrt{29} m/s
Regards
Sumit
