Force is responsible for all changes in motion.
Answer:
A
If Car A has half the mass of Car B, then it must have twice the velocity to come to a stop when colliding.
Answer:
(a)
(b)
(c)
(d)
Explanation:
The linear momentum is defined as:
(1)
Where m is the mass and v is the velocity
<em>a.) </em><em>A proton with mass moving with a velocity of . </em>
Replacing those values in equation (1) it is gotten:
So, it has a linear momentum of
<em>b.)</em><em> A 1.6 g bullet moving with a speed of 374m/s to the right.</em>
Notice that in this case it is necessary to express the mass of the bullet in terms of kilograms:
⇒
<em>c.) </em><em>A 8 kg sprinter running with a velocity of 11.8 m/s. </em>
<em>d.) </em><em>Earth () moving with an orbital speed equal to 29700 m/s.</em>
