    Question:

    A force of 10 Newton starts acting on a body kept at rest. Find the momentum of the body at 5 seconds after the four starts acting?​

    __________________________________________________________

    Answer:

    Let ‘m’ be the mass of the body. The acceleration be ‘a’.  

    F = ma

    => 10 = ma

    => a = 10/m

    Initial velocity at t= 1 will be zero

    Velocity after 1 s = at = 10/m Ns


    Momentum after 1 s is, p1 = mv1 = m(10/m) = 10 Ns

    Velocity after 5 s is, v5 = at = (10/m) x 5 = 50 Ns or 50 Kgm/s
