A skier squats low and races down an 11 degree ski slope during a 2s interval the skier accelerates 1.2m per sec squared what is the horizontal component of the skier's acceleration?

It doesn't matter how long she maintains her acceleration.
As long as she continues to accelerate at 1.2 m/s2 parallel to the slope,
the vertical component of her acceleration is
1.2 sin(11°) = 0.229 m/s2 (rounded)
and the horizontal component is
1.2 cos(11°) = 1.178 m/s2(rounded)

What are three components needed to find an object acceleration?
Using the definition of acceleration as change of speed / time, you basically need to know: * A time interval during which the object accelerates. * The velocity at the beginning of this time interval. * The velocity at the end of this time interval.
What is the formula to determine the acceleration of an object moving in a strait line?
Acceleration = (speed at the end of some time interval minus speed at the beginning of the interval)/(length of the time interval)
How to find acceleration?
Acceleration has two parts ... its size and its direction.To find the size (magnitude):-- pick a time interval-- measure the speed at the beginning of the interval-- measure the speed at the end of the interval-- subtract the speed at the beginning from the speed at the end-- divide that difference by the length of the time interval-- the result is the magnitude of acceleration during that time interval
How do you calculate a objects acceleration?
Acceleration = (change in speed) divided by (time interval)
Is Acceleration is the magnitude of average velocity?
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.
What increases speed during a given interval of time?
acceleration
Which is an increase of speed during a given interval of time?
"acceleration"
What will be the acceleration of a car moving in a uniform acceleration?
You need the initial and final velocities, and time interval to answer this question.
What is an increase of speed during a given interval of time?
Acceleration. Deceleration is a decrease of speed during a given interval of time.
An increase of speed during a given interval of time is called negative acceleration?
No, it's only the acceleration. By (-)ve acceleration ,it means retardation or deceleration..

Derive the equation for instantaneous average acceleration vector?
You have a contradiction in your question. Instantaneous acceleration is the acceleration at a certain moment in time. Average acceleration is the average over a time interval.
