100 meters per second

Force = (Change in Momentum $\div$ $-:$ time)

$F \times t = (m_{2} \times v_{2} - m_{1} \times v_{1})$ $Fxxt = (m_2xxv_2- m_1xxv_1)$

As the object starts from rest

$F \times t = (m \times v)$ $Fxxt = (mxxv)$

Therefore

$v = \frac{F \times t}{m}$ $v = (Fxxt)/m$

$v = \frac{350, 000 \times 2}{7000}$ $v = (350,000xx2)/7000$ = $100 \frac{m}{s}$ $100 m/s$
