From the calculation and the momentum of the body, the velocity is 62 m/s
<h3>What is momentum?</h3>
The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.
Hence;
7440 kg-m/s = 120 kg * v
v= 7440 kg-m/s/120 kg
v = 62 m/s

Answer:
The answer is It has inertia
Explanation:
I just got it correct on E2020
The answer is 4.
The speed of light is faster in the air than in the glass, because a wavelength can be refracted in glass. Because the speed increases when the light wave passes from glass into air, the wavelength will also increase.
Your position at time
, relative to the stop line:

The Porsche's position:

a. You pass the Porsche immediately after the time it takes for
:

at which point you both will have traveled 7.8 m from the stop line.
b. The equation in part (a) has two solutions. The Porsche passes you at the second solution of about
, at which point you both will have traveled 29 m.
c. At time
, the Porsche is moving at velocity

so that at the moment it passes you, its speed is 13 m/s, which is about 46.8 km/h and below the speed limit, so neither of you will be pulled over.
Current is split among different branches of wires, or voltage is equal throughout?
