Calculate the magnitude of the linear momentum for each of the following cases

a.) a proton with mass 1.67 ×10−27 kg moving with a velocity of 6 x 106 m/s. answer in units of kg x m/s.
b.) a 1.6 g bullet moving with a speed of 374m/s to the right. answer in units of kg x m/s.
c.) a 8 kg sprinter running with a velocity of 11.8 m/s. answer in units of kg x m/s.
d.) earth (m=5.98 x 1024 kg) moving with an orbital speed equal to 29700 m/s. answer in units of kg x m/s.

(a)

(b)

(c)

(d)

Explanation:

The linear momentum is defined as:

 (1)

Where m is the mass and v is the velocity

a.) A proton with mass moving with a velocity of .

Replacing those values in equation (1) it is gotten:

So, it has a linear momentum of

b.) A 1.6 g bullet moving with a speed of 374m/s to the right.

Notice that in this case it is necessary to express the mass of the bullet in terms of kilograms:

⇒

c.) A 8 kg sprinter running with a velocity of 11.8 m/s.

d.) Earth () moving with an orbital speed equal to 29700 m/s.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
