Well you didn’t give answer choices but this sounds like... he’s stereotyping? Stereotypes... ageism....
Answer:
Explanation:
As the velocity of light is constant so the acceleration of the light is equal to zero.
a=
dt
dv
Answer:
Explanation:
I can tell you what the answers for the middle column are, but if you don't know how to solve total energy problems, they won't make any sense to you at all.
First row, KE = 0
Second row, KE = 220500 J
Third row, KE = 183750 J
Fourth row, KE = 205800 J
That's also not paying any attention to significant digits because your velocity only had 1 and that's not enough to do the problem justice. I left all the digits in the answer. Round how your teacher tells you to.
By energy conservation we will say
as we know that
also we have
now we will have
Answer:
5.71428571422 m/s
Explanation:
u = Initial velocity = 20 m/s
v = Final velocity
s = Displacement
a = Acceleration
Time taken = 15-1 = 14 s
Distance traveled in 1 second =
The speed as she reaches the light at the instant it turns green is 5.71428571422 m/s
