A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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.


When does acceleration occur?

Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)


Can Bodies With Different Velocities Have The Same Acceleration?

Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.


What is the average acceleration between 0 seconds and 4 seconds?

what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)


If a car goes in 6.8 seconds how do you figure out the acceleration?

Acceleration= distance / velocity squared


What is the vehicles velocity after 1.0 seconds?

That depends on its initial velocity and its acceleration. V1 = V0 + a * t


What is the acceleration of a car with a steady velocity of 100 km per hour for 100 seconds?

If velocity is steady and doesn't change, then there is 0 acceleration.


What is the acceleration of a carthat moves at a steady velocity of 100 km an hour for 100 seconds?

Zero. Anything that moves at a steady velocity has no acceleration by definition, because acceleration is defined as rate of change in velocity.


What is the average velocity of the particle from rest to 9 seconds?

The answer will depend on its acceleration.


A rolling ball has an initial velocity of 5 meters per second 30 seconds later its velocity is 2 meters per second What is the acceleration of the ball?

The acceleration of the ball can be easily found using the kinematic equation if = vi + at. Where vi = initial velocity, if = final velocity, a = acceleration, and t = seconds. The acceleration is -0.1 m/s^2.


What is the formula for change in velocity?

A change in velocity is known as acceleration. Acceleration, in meters per second squared, is equal to velocity, in meters per second, divided by time, in seconds.


''How do calculate velocity?

To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
