It is possible for on object to be going at 100 miles per hour, but still have a velocity. This is because the object going at 100 miles per hour has speed, which is a scalar quantity, which is defined by only magnitude, but the velocity of the object can be 0, since velocity is a vector quantity which is defined by both magnitude and direction.
Since this object only has magnitude and no direction (which is not given), then the velocity can be 0
( 1.05 x 10¹⁵ km ) x ( 1 LY / 9.5 x 10¹² km ) x ( 1 psc / 3.262 LY ) =
(1.05) / (9.5 x 3.262) x (km · LY · psc) / (km · LY) x (10¹⁵⁻¹²) =
(0.03388) x (psc) x (10³) =
33.88 parsecs
The distance between object P1 and its image formed is determined as 36 m.
<h3>
Distance of the image</h3>
The distance of the image formed by object P1 is calculated as follows;
In a plane mirror; object distance = image distance
image distance of P1 = 18 m
distance between object and image = 18m + 18 m = 36 m
Thus, the distance between object P1 and its image formed is determined as 36 m.

(a)
The magnitude of the linear momentum of an object is given by
where
m is the object's mass
v is its speed
In this case, we have
(mass of the proton)
(speed of the proton)
So, the momentum is
b) 7.0 kg m/s
In this case, we have
m = 16.0 g = 0.016 kg (mass of the bullet)
v = 435 m/s (speed of the bullet)
By applying the same formula, the linear momentum is
c) 797.5 kg m/s
In this case, we have
m = 72.5 kg (mass of the sprinter)
v = 11.0 m/s (speed of the sprinter)
By applying the same formula, the linear momentum is
d)
In this case, we have
(mass of the Earth)
(speed of the Earth)
By applying the same formula, the linear momentum is
