Hey there,
Momentum (p) = mv
Where m is the mass and v is the velocity of body.
Change in momentum = mv2 - mv1 = m(v2 - v1) = m(∆v)
To calculate this we require mass and the change in velocity. Let's calculate the change in velocity.
Using the formula F=ma
100 = 2*a
a= 50 m/s^2
Now we know that acceleration is the rate of change of velocity or a = ∆v/t
∆v = a*t = 50*10 = 500 m/s
Change in momentum ∆p = 2*500 = 1000 kgm/s
HOPE YOU GOT IT
