Answer:
15 miles /seconds
Explanation:
Distance = 600m
Time = 40 seconds
Speed=?
Simplify
An object travels a distance d with acceleration a over a period of time t according to the equation: d = at² After 2.3 seconds

Answer:
E=12.2V/m
Explanation:
To solve this problem we must address the concepts of drift velocity. A drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field.
The equation is given by,
Where,
V= Drift Velocity
I= Flow of current
n= number of electrons
q = charge of electron
A = cross-section area.
For this problem we know that there is a rate of 1.8*10^{18} electrons per second, that is
Mobility
We can find the drift velocity replacing,
The electric field is given by,
