    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
