    Answer:4.0625m/s

    Explanation:

    force(f)=325N

    Time(t)=10seconds

    Mass(m)=800kg

    Initial velocity(u)=0

    Final velocity(V)=?

    F=(v-u) ➗ t

    325=800(v-0) ➗ 10

    325=800v/10

    Cross multiplying we get

    800V=325 x 10

    800V= 3250

    V=3250/800

    V=4.0625m/s
