    Answer:

    Step-by-step explanation:

    F = P / Δt

    P = F * Δt

    P = 50 * 3

    P = 150 kg*m/s

    Step-by-step explanation:

    momentum =mass * velocity. eql.1

    we know that , force=mass *acceleration

    take g=10m/s2

    50=mass*10

    mass=5kg

    then, acceleration =v-u/t

    body in rest when force is applied then the initial velocity is equal to zero

    a=v-0/t

    10=v/3

    v=30m/s

    put up the value of velocity and mass in equation first

    momentum=5*30

    m=150kgm/s2
