given data:
mass = 2000kg
initial velocity = 10m/s
final velocity = 16m/s
time = 12seconds
so, by using 1st eqn of motion we will get acceleration :
v = u + at
16 = 10 + 12a
6 = 12a
a = 6/12
a = 1/2 or 0.5 m/s^2
initial momentum is = mass × initial velocity = 2000kg × 10m/s = 20000kgm/s
final momentum = mass × final velocity = 2000kg×16m/s = 32000kgm/s
force = mass × acceleration = 2000kg × 1/2 m/s^2 = 1000N or 1000kgm/s^2.
hope it helps
