If your average speed for a 3 hour trip is 45 miles per hour what was the distance of your trip?
3 x 45 = 135 miles total distance. You are averaging 45 miles per hour over the 3 hour period.
The kinetic energy of the ball is at its maximum when it is initially thrown, as it has the highest speed at that point. The gravitational potential energy of the ball is at its maximum when the ball reaches its highest point in the throw, where its height above the ground is greatest.
If both the mass and velocity of a ball is tripled the kinetic energy is increased by a factor of?
When both the mass and velocity of a ball are tripled, the kinetic energy increases by a factor of 9. This is because kinetic energy is directly proportional to the square of the velocity, and also directly proportional to the mass. So tripling both the mass and velocity results in the kinetic energy increasing by 3^2 = 9 times the original value.
increase as kinetic energy is directly related to temperature. The molecules would move faster, increasing collisions and thermal energy, causing an increase in body temperature.
Liquid, Solid, Gaseous, Plasmas, and Bose-Einstein condensates.
What is an order of magnitude?
An order of magnitude is a measure of the size or scale of a value or quantity. It represents a factor of 10 difference in numerical value. For example, if one value is one order of magnitude larger than another, it is 10 times greater.
Kinetic energy is the force that needs to be dissipated in a collision?
Kinetic energy is the energy possessed by an object due to its motion. In a collision, this energy must be dissipated through deformation or other mechanisms, which can result in damage or displacement of the objects involved in the collision. The amount of kinetic energy present in a system is proportional to the mass and velocity of the objects in motion.
A collision in which the total momentum and kinetic energy remain constant?
An elastic collision is one in which both momentum and kinetic energy are conserved. In an elastic collision, the total kinetic energy before the collision is equal to the total kinetic energy after the collision. This type of collision is characterized by no energy being lost or dissipated as heat or sound.
What is the equation to calculate density?
Density is calculated by dividing an object's mass by its volume. The equation is: Density = Mass / Volume. The resulting value is typically expressed in units such as grams per cubic centimeter (g/cm^3) or kilograms per cubic meter (kg/m^3).
Well it is a question of Projetile Motion. Whenever you project an object at some angle with horizontal it traces a curved path. Suppose 'x' be the angle with horizontal, 'm' be its mass, 'u' be its initial velocity. You might be knowing that any vector can be resolved into horizonal and vertical component. Here horizontal component of velocity will be ucosx and vertical will be usinx. At highest point the vertical component of the velocity will become zero. Hence it will have no velocity in vertically upward direction. It will only have velocity in horizontal direction which will be 'ucosx'.(The horizontal component of initial velocity will not affected by force of gravity and hence it will be constant throughout the motion.) So kinetic energy at highest point is: KE=0.5*m*(ucosx)^2 KE=0.5*50*(200*cos60)^2=25*10000=250000 J

A 1-kilogram ball has a kinetic energy of 50 joules what is the velocity of the ball?
To find the velocity of the ball, you can use the formula for kinetic energy: KE = 1/2 * mass * velocity^2. Therefore, 50 J = 1/2 * 1 kg * velocity^2. Solving for velocity, you get velocity = √(2 * 50 J / 1 kg) = 10 m/s.
How do you caculate the momentum of an object?
The momentum of an object can be calculated by the formula mv=momentum where m is the mass and v is the velocity.
Here is another formula that may be of some help (it is the formula for the impulse-momentum relationship):
Ft=(delta)(mv)
F stands for the impact force and t stands for the impact time. Ft together equals the impulse. m stands for the mass and v stands for the velocity. (delta)(mv) together equals the change in the momentum.
What is kinetic and potiential energy?
The definition for Potenial Energy- is stored up energy due to its position the definition for Kinetc Energy- is energy an object has due to its motion. [motion is moving]
Here are some examples of Potenial Energy
a man on top of a slide, a cup on a table, and a pencil on a desk.
remember potenial energy is something that's stay still or don't move
Here are some Examples of Kinetc Energy
a moving car, a moving bus, amoving train, and a moving truck.
remember kinetc energy is something that moves .. another word for move is motion. one mor example: water in the ocean is moving.
Does fire have Kinetic or potential energy?
A blazing bonfire is the release of chemical energy.
Kinetic energy is that energy that is part of a body because of its motion.
Potential energy is that energy that is part of a body because of its position in a gravity field. kinetic and potential energy can interchange.
However the energy in a bonfire is trapped radiation energy (sunlight) stored chemically in the substance of the wood and released by a chemical reaction.
30 m/s
The acceleration due to gravity is 9.81 m/s2.
So, after the 1st second, it is traveling 9.81 m/s.
After the 2nd second, it is traveling 19.62 m/s.
After the 3rd second, it is traveling about 30 m/s.
Converting km per hour to cm per second?
To convert km per hour to cm per second, you need to multiply the km per hour value by 27.7778. This is because there are 100,000 centimeters in a kilometer and 3,600 seconds in an hour. So, 1 km/h is equivalent to approximately 27.7778 cm/s.
What causes acceleration of an object?
Acceleration of an object is caused by the application of a force on the object in the direction of acceleration. This force can be due to factors such as gravity, friction, or propulsion. The greater the force applied, the greater the acceleration of the object.

An object in 3 dimension space is called?
An object in 3-dimensional space is called a three-dimensional object or a 3D object. These objects have length, width, and height, making them appear solid and taking up space in all directions.
To convert frames per second (fps) to miles per hour (mph) in a video, you need to know the distance covered in one frame and the duration of the video in seconds. Once you have those values, you can use the formula: mph = (fps * distance per frame * 3600) / seconds in video. This will give you the speed in miles per hour.
List all 5 states of matter in order of the highest kinetic energy to the lowest kinetic energy?
First, Gas- It has the most kinetic energy because it moves more freely. Second, liquid - It has okay kinetic energy. Then its Solid with the least kinetic energy.
