To find the time it takes for the ball to reach its highest point, we can use the following kinematic equation: vf = vi + a*t= 2.02 seconds.

where

vf = final velocity (0 m/s, since the ball, is at its highest point)

vi = initial velocity (25.0 m/s, upward)

a = acceleration (9.8 m/s^2, downward)

t = time

Substituting in the given values, we get: 0 = 25.0 + (-9.8)t

Solving for t, we get: t = 25.0 / -9.8 = 2.55 seconds

x = vi*t + (1/2)at^2

where

x = distance fallen (2.0 m, the initial height)

vi = final velocity (0 m/s, since the ball is at its highest point)

a = acceleration (9.8 m/s^2, downward)

t = time

Substituting in the given values, we get:

2 = 0t + (1/2)(-9.8)*t^2

Solving for t, we get:

t = √(2/(-9.8)*(1/2)) = 2.02 seconds

If there is a negative point charge of -q at location (r), the magnitude of the electric field at that location would be: E = k * |-q| / r^2 and the direction would be away from the point charge.

 Magnitude is "distance or quantity." In a kinematic sense, it displays the absolute or relative direction or magnitude of movement of an object.  Size is related to both quantity and distance.

The magnitude of the electric field (E) at a point in space due to a negative point charge (q) is given by Coulomb's Law: E = k * q / r^2, where k is the Coulomb constant (approximately 8.99 x 10^9 N * m^2/C^2) and r is the distance from the point charge to the location where the electric field is being calculated. The direction of the electric field is away from the point charge.

So, if there is a negative point charge of -q at location (r), the magnitude of the electric field at that location would be: E = k * -q / r^2 and the direction would be away from the point charge.

The spring constant of this spring is -22,275 N/m.

Spring constant is a physical constant that describes the stiffness of a spring. It is used to calculate the force that is needed to extend or compress a spring by a given amount.

Hooke's law states that the force applied to a spring (F) is proportional to the displacement of the spring (x). The equation is:
F = -kx
where k is the spring constant.
To calculate the spring constant (k) of the spring, we need to rearrange the equation to isolate k:
k = -F/x
To solve for the spring constant, we need to know the force applied to the spring. Since we know that the mass hung from the spring is 70 g, we can calculate the force with the equation F = mg, where m is the mass of the object and g is the acceleration due to gravity.
F = 70 g * 9.81 m/s^2
F = 686.7 N
Now we can plug in the values for F and x into the equation k = -F/x to calculate the spring constant:
k = -686.7 N / 0.0308 m
k = -22,275 N/m

An electrically charged particle or object creates an electric field, which is the area of space where an electric charge would experience force. Bring another charge into the electric field to observe the electric field, which is present everywhere in space. If the charges are separated enough from one another, the electric field can be practically approximated as zero.

Electric fields are a vector quantity that can be pictured as arrows pointing in the direction of or away from charges. The directions of the lines are either radially outward, away from a positive charge, or radially inward, toward a negative charge.

Part A:

If we write the argument of the cosine function as,

Answer:

is inversely proportional to the square of distance between the two objects

The velocity midway between P and Q is 25 m. Based on the direction of the displacement, the average velocity might either be positive or negative.

We say an object has uniform acceleration if its speed (velocity) is growing at a constant pace. Acceleration happens at a steady rate. A car's acceleration is not uniform if it accelerates quickly, then slows down, and then accelerates again.

In terms of time, an object or particle's movement is expressed vectorially as velocity. The recognized measurement of velocity magnitude is the meter per second (m/s) (also known as speed). A different way to indicate velocity is in centimeters per second (cm/s).

The velocity midway between P and Q can be found using the average velocity formula. Average velocity is given by:

Average velocity = (Initial velocity + Final velocity) / 2

In this case, the initial velocity is 20 m/s and the final velocity is 30 m/s. Therefore, the average velocity is:

Average velocity = (20 m/s + 30 m/s) / 2 = 25 m/s

So the velocity midway between P and Q is 25 m/s.
