Explanation:
From the exercise we know that the ball strikes the building 16m away and its final height is 8m more than the initial
Being said that, we can calculate the initial velocity of the ball
a) First we analyze its horizontal motion
(1)
That would be our first equation
Now, we need to analyze its vertical motion
Knowing in our first equation (1)
Solving for t
So, the ball takes to seconds to get to the other building. Now we can calculate its <u>initial velocity</u>
b) To find the <u>magnitude of the ball just before it strikes the building</u> we need to calculate its x and y components
So, the magnitude of the velocity is:
c) The <u><em>direction of the ball</em></u> is:
Explanation:
The electric field at a distance r from the charged particle is given by :
k is electrostatic constant
if r = 2 m, electric field is given by :
If r = 1 m, electric field is given by :
Dividing equation (1) and (2) we get :
So, at a point 1 m from the particle, the electric field is 4 times of the electric field at a point 2 m.
