    Answer:

    Ft

    Explanation:

    We are given that

    Initial velocity=u=0

    We have to find the magnitude of p of the momentum of the particle at time t.

    Let mass of particle=m

    Applied force=F

    Acceleration, a=\frac{F}{m}

    Final velocity , v=a+ut

    Substitute the values

    v=0+\frac{F}{m}t=\frac{F}{m}t

    We know that

    Momentum, p=mv

    Using the formula

    p=m\times \frac{F}{m}t=Ft
