If we need momentum then we should have mass ( m ) and velocity ( v )
that we have,
p = momentum ( ? )
m = 5kg
u = 0m/s
a = 2m/s^2
s = 4m
v^2 - u^2 = 2as
v^2 - 0 = 2*2*4
v^2 = 16
:. v = 4
p=mv
p=5 * 4
p = 20 kgm/s
that we have,
p = momentum ( ? )
m = 5kg
u = 0m/s
a = 2m/s^2
s = 4m
v^2 - u^2 = 2as
v^2 - 0 = 2*2*4
v^2 = 16
:. v = 4
p=mv
p=5 * 4
p = 20 kgm/s

How can you say the unit of velocity to m/s^2
sorry it was written by mistake
ohh okay. . but the right answer is 20kgm/s
i thought that i was incorrect as i was confused in which is the rest state 'u' or 'v'......
i'll edit it
its ok bro. .and thanks for help
well
