Answer 2

Explanation:

Explanation:

The equation for momentum is

p

=

m

v

Where:

p

=

momentum

m

=

mass of object in kg

v

=

velocity of object

By simply plugging in the numbers into the equation:

1000

k

g

×

35

m

s

You get

=

35000

k

g

m

s

or

35000

N

[Do take note that
