What else can I help you with?
Why there is no acceleration along x axis during projectile motion?
There is no force that acts upon the object in that direction. Gravity only acts on the y axis. Though there is some wind resistance that does cause a negative acceleration in the x direction. You are probably just being told to ignore this as it is usually negligible.
What is the definition of decreasing velocity?
Velocity is a vector so it has magnitude (size) and direction. so to change velocity all you need to do is slow down or speed up or change direction. This is also known as acceleration which is the rate of change in velocity.

The equation used to find acceleration is?
There are several different equations that can be used to find acceleration. The right one to choose depends on what information is given or measured. Examples: -- You're given the mass of an object and the force acting on it. Acceleration = (force) divided by (mass) -- You're given the starting and ending speed of a car, and how much time it was moving. Average acceleration = (change in speed) divided by (time for the change) -- An object started out from rest. You're told how far it moved and how long it took. Average acceleration = (2 x distance) divided by (time squared)
How is the mass different from weight?
Mass is the amount of matter that something is made of. Weight is a measure of the gravitational force exerted on an object usually by the earth. Weight can change but Mass cannot. Mass always stays the same
is upthrust a scalar or vector quantity?
You've already told us its direction. As soon as you tell us its magnitude, we'll have a vector.
What is the acceleration of a car that maintains a constant velocity of 100km per h for 10 seconds?
Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.
How to calculate if time and initial velocity are given?
This is difficult. We are not told what it is we are to calculate. We are not told how the velocity is changing (which it does, implied by the word "initial"). Suggest re-writing the question.
What is the object pronoun in the sentence the boy told her that he lost his new jacket?
The object pronoun is her, the direct object of the verb 'told'.
How much force does it take to accelerate an object weighing 2 ounces to 440 fps in under a second?
Any force at all will do it. The question doesn't specify the magnitude of the acceleration, only the final velocity. We're not told how much time we have to do the job ... does it need to happen in the next 5 seconds, or do we have all day to work on it ? The sooner it's required, the more force we'll need to use. But given enough time, any force, no matter how small, will accomplish the task.

What is force fluid?
This means to drink as many fluids as you can, more than you normally would, when you are sick. I don't understand the physiology behind it but it is something a nurse has told me before.
What is the indirect object in the teacher told the class a story?
"The class" is the indirect object. In English, the indirect object is usually something that could also be expressed by putting "to" in front of it. The sentence could be rephrased "The teacher told a story to the class."
How do you diagram Ellen told David the story?
This sentence can be diagrammed as follows: Subject (Ellen) - Verb (told) - Direct Object (the story) - Indirect Object (David).
Is told a transitive or intransitive verb?
Told is an intransitive verb because it doesn't travel from one place to another.
A 70 kg cyclist develops 210 watts of power while pedaling at a constant velocity of 7.0 meters per seconds east What average force is exerted eastward on the bicyclist to maintain his constant speed?
A convoluted but clever question, designed to really test one's comprehensionof some basic concepts.The cyclist's kinetic energy is [ 1/2 M V2 ] = [ 35 x 49 ] = 1,715 joules. This facthas no applicability whatsoever to the solution of this question.Ordinarily, in the simplified world of basic physics, air resistance and other dissipativefactors are neglected, and no force is required to maintain constant velocity. But here,it's pretty clearly implied that the cyclist and his machinery are leaking energy to thesurroundings, and he has to keep coming up with more energy just to keep movingat constant speed in a straight line. We're even told that the rate of energy loss is210 watts = 210 joules per second.Energy delivered to the system in the form of mechanical work is quantitatively equal to (force) x (distance).The rate at which the work is delivered is (force) x (distance/time) = (force) x (speed).We know the rate (210 joules per second), and we know the speed (7 meters per second).Work/time = Power = Force x speed210 = F x 7F = 210/7 = 30 newtons . (about 6.75 pounds of force)

Is tell a transitive?
"Tell" can be both transitive and intransitive, depending on the context. When used with an object, such as "He told a story," it is transitive. When used without an object, like "He told me," it is intransitive.
