Answer:
D) 30°
Explanation:
This is in accordance to the Gauss Law which states that, <em>the electric flux through any closed surface is equal to the total charge enclosed by the surface divided by the permittivity of free space.</em>
Mathematically given as:
where
θ = the angle between the electric field lines and area vector normal to the surface.
When the area vector has formed an angle of 60° then the plane is at 30° and we know <em>cos 60° = 0.5</em>

In order to know how long it has been falling for you take the final velocity "49m/s" and divide it by the acceleration "9.8m/s" and get 5, since you have been using seconds in the calculations the answer is 5 seconds. (Fun fact, it is actually 9.82m/s per second since it accelerates and they rounded it down.)
Answer:
Final velocity of the car will be -9.28 m/sec
Explanation:
We have given that the car starts from the rest so initial velocity of the car u = 0 m /sec
Acceleration of the car 
in negative direction so acceleration will be 
From first equation of motion we know that
v = u+at
So 
So final velocity will be -9.28 m/sec
