Answer:
The y-component of the electric force on this charge is 
Explanation:
<u>Given:</u>
- Electric field in the region,
- Charge placed into the region,
where, 
are the unit vectors along the positive x and y axes respectively.
The electric field at a point is defined as the electrostatic force experienced per unit positive test charge, placed at that point, such that,
Thus, the y-component of the electric force on this charge is

Answer:
The ball will hit the ground in 2.73 s
Explanation:
Hi there!
f(t) is the height of the ball at time "t". We need to find the value of "t" for which f(t) = 0.
f(t) = 0 Then:
-16 · t² + 40 · t + 10 = 0
Solving the quadratic equation using the quadratic formula (a = -16, b = 40, c = 10):
t = -0.23 s and t = 2.72 s
Since time can´t be negative, be discard that value.
The ball will hit the ground in 2.73 s.
Have a nice day!
