Mass (kg) 4.0
Applied Force (N) 20.0
Surface Friction 0
On the simulation click on the last circle of the velocity time graph this should be at time = 5.0 seconds. What is the velocity of the box at 5 seconds?

25 m/s

Explanation:

First of all, we can find the acceleration the object by using Newton's second law of motion:

where

F = 20.0 N is the net force applied on the object

m = 4.0 kg is the mass of the object

a is its acceleration

Solving for a, we find

Now we know that the motion of the object is a uniformly accelerated motion, so we can find its final velocity by using the following suvat equation:

where

v is the final velocity

u = 0 is the initial velocity

is the acceleration

t = 5 s is the time

By substituting,

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example
