An electron has an initial speed of 4.18 x 10^5 m/s.
If it undergoes an acceleration of
3 x 10^14 m/s^2, how long will it take to reach
a speed of 5.19 x 10^5 m/s?
Answer in units of s.
How far has it traveled in this time? Answer in units of m.

Initial velocity, u= 4.18E^5 m/s

Final velocity, v= 5.19E^5 m/s

a = 3E^14 m/s²

from,

a = (v - u)

t

t = (v - u)

a

t = (5.19E^5 - 4.18E^5)

3E^14

t = 3.37 × 10^-10s

side note; the E represents 10 power.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
