Question:

A ball has a 17 J of kinetic energy and lB mechanical energy is 25 Joule

a. Find the gravitational potential energy of the ball.  

b. if the ball has a mass of 3.2 kg, what is its height above the ground?  

c. What is the speed of the ball?

Answer:

a.  = 85

b. h = 0.25 m

c. = 3.26 m/s

Explanation:

Part A

PEgrav = m ו g • h

In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity. So, to find:

GPE = ME - KE = 25 - 17 = 85

Part B

The formula simplifies to: h max = h + V₀² / (2 × g) and the time of flight is the longest.

The vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.

The equation may be written as:

    GPE = mgh

    8 = 3.2 × 10 × h

    h = 0.25 m

Part C

The ball speed is calculated by dividing the distance by the time. If the time was 3 seconds, the average speed will be 60/3 = 20 feet per second (6.1 m/sec). KE = 1/2 MV²

            17 = 1/2 × 3.2 x V²

            V = 17 ÷ 1.6

Note, this is only the average ball speed, the speed of the ball at the time of release would be greater.

Answers

The equation v=rω says that the tangential speed v is proportional to the distance r from the center of rotation. ... This makes sense because a point farther out from the center has to cover a longer arc length in the same amount of time as a point closer to the center.

A mercury in barometer shows a height of 70cm.What height would be shown in the barometer at the same place if water density 1.0×10³kg/m³ is used(denssity of mercury=13600kgm-³)​

Answers

Answer:

P = d g h      pressure due to density of liquid of height h

d1 g h1 = d2 g h2       since P1 equals P2

d1 h1 = d2 h2      and the density of Hg is 13.6 times that of water

h2 = (d1 / d2) * h1 = 13.6 * 70 cm =  952 cm or 9.52 m

The law of conservation of energy states that energy is always conserved, and cannot be destroyed.

At the top of the hill, the ball is at the maximum height. Because the equation for gravitational potential energy is ([tex]U_{g}[/tex] = mgH), we can safely conclude that the GPE at A, the top of the hill, is the greatest in all 4 options.

Now, what about Kinetic Energy? Recall the law of conservation of energy. At the point where Gravitational Potential Energy is the lowest, Kinetic Energy will be the highest. Total energy is always conserved, and so it is logical that KE will increase to compensate for GPE decreasing. Therefore, we know that at point C, the ball will have the greatest Kinetic Energy. Because this point is the lowest point in the hill, the ball will have the lowest possible GPE and therefore the largest possible KE out of the 4 options.

4. A

5. C

Answer:

A.1

Explanation:

The length of the y-component of the vector plotted in the given question would be 1. Thus, the correct option is A.

What is a vector plot?

A vector field can be defined as an assignment of a vector to each point in the subset of space. For instance, a vector field in the plane can be easily visualized as a collection of arrows with a given magnitude and direction of a particle, each line or arrow attached to a point in the plane of space.

Vector plots are used to create vector lines between any two points or from one point in space to the specified angle direction and with the selected magnitude and direction of the quantity or quality.

In the given graph, the Y-component is the vertical line or vertical component. The value of the y-component of the vector plotted is 1.

Therefore, the correct option is A.
