The part B of the question is missing and it is;
b) What is the height between the two window ledges?
Answer:
A) 20.76 m/s
B) 161.52 m
Explanation:
A) To calculate the initial speed we use the formula from Newton's first law of motion:
v = u + at
Making u the subject gives;
u = v - at
Where;
v is the final velocity which is the speed when Jill sees the pot = 60 m/s
u is the initial velocity which is the speed when Jack sees the pot go by
t is the time between the two observed events = 4 s
a in this question is acceleration due to gravity = 9.81 m/s².
Plugging in the relevant values into the initial velocity equation gives;
u = 60 - (9.81 × 4)
u = 20.76 m/s
B) To get the height difference, we will use the formula;
(y1 - y0) = ut + ½at²
Thus, plugging in the relevant values, we have;
y1 - y0 = (20.76 × 4) + (½ × 9.81 × 4²)
(y1 - y0) = 161.52 m
The net force on the -4.0μC object as a result of this net field will be -10.4 N.
<h3>What is the charge?</h3>
The matter has an electric charge when it is exposed to an electromagnetic field is known as a charge.
The electric field intensity is found as the force per unit charge.
Electric field intensity on the positive charge:

Electric field intensity on the negative charge:

The net charge is the algebraic sum of the two charges;

Hence, as a result of this net field, the net force on the -4.0C object will be -10.4 N.
