Best Answer

The acceleration cannot be determined with this information. The beginning and ending velocity needs to be known. You can determine her average velocity, however.

average velocity = displacement/time = (9mi - 3mi)/3s = 6m/3s = 2m/s

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

An inline skater traveling in a straight line goes from 3ms to 9ms in 3 s. what is the acceleration?

Calculate the difference in velocity, Then divide that by the time. The result will be the acceleration, in this case, in meters per second squared.

An ice skater glides around a rink at a constant speed of 2 ms is the skater acceleratng explain your answer?

The the skater is accelerating. Acceleration is the rate at which an object changes its velocity. Velocity is a measure of speed and vector (direction). Even though the skater is traveling at a constants speed, the skater is going in a circle around the rink so the direction is changing. Therefore the velocity is changing. Therefore the skater is accelerating.


An ice skater glides around a rink at a constant speed of 2m s is the skater accelerating?

Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.

A 60-kg skater pushes off from a wall with a force of 300 N What is her acceleration?

her acceleration would be 5 m/s2 because F=ma, or Force=mass x accelration, therefore 300 N= 60kg x acceleration.
