c)newton- second
d)non of the above

the first answer will be mark as brainliest ​

Answer 1

Explanation:

b)newton/second......

Answer 2

Answer:

The SI unit of momentum is Newton-Second i.e.option(c).

Explanation:

First, let's see how force is given.

$F=m\frac{v}{t}$         (1)

Where,

F=force acting on a body. Its unit is Newton.

m=mass of the body

v=velocity with which the body is moving

t=time required by the body to produce a certain change. Its unit is second.

And the momentum of the body is given as,

$P=mv$            (2)

By putting equation (2) in equation (1) we get;

$F=\frac{P}{t}$

$P=Ft$

$P=Newton-Second$

Hence, the SI unit of momentum is Newton-Second i.e.option(c).
