    Write your comment here...yeah,we all know the formula of momentum i.e-momentum =mass × velocity
    but first we know that the highest point i.e-u cos theta

    Given: Mass of body = 2 kg, velocity = 15 m/s, θ = 70°

    Formula: 1) At highest point velocity = u cos θ

    2) Momentum = mass x velocity

    Solution:

    1) At highest point velocity = 15 x cos 70

    = 5.13 m/s

    2) Momentum = mass x velocity

    = 2 x 5.13

    = 10.26 kg ms-1

    The momentum of a body at its highest point is 10.26 kg ms-1
