you need to know what the finishing speed is. get the finishing speed and take 44 away from it.
then divide that answer by 12.
The general formula is:
a = (v - u) / t
where : a = acceleration
v = final velocity
u = initial velocity
t = time taken

What is the increase of velocity over a period of time is?
Acceleration is the rate of change of velocity over a period of time. When an object's velocity increases over a period of time, it is experiencing positive acceleration.
What are the effects of acceleration due to gravity on the time period of a pendulum?
The period of a pendulum (in seconds) is 2(pi)√(L/g), where L is the length and g is the acceleration due to gravity. As acceleration due to gravity increases, the period decreases, so the smaller the acceleration due to gravity, the longer the period of the pendulum.
Acceleration is defined as a change in velocity over time if a runner increases velocity from 2 m s to 4 m s over a period of 20 seconds what is the acceleration?
Assuming that acceleration is constant during that time, just divide the change in speed by the time.
How is acceleration calcuated?
Dividing change of velocity by the time it takes to change the velocity. If acceleration is not constant, this will give you the average acceleration during the period; to get the instantaneous acceleration, you have to take the derivative of the velocity.
What is her acceleration if 'acceleration is defined as a change in velocity over time. If a runner increases velocity from 2 ms to 4 ms over a period of 20 seconds?
It is 0.1 metre per second-squared.
When elevator move down with acceleration pendulum of bob what is effect on time period?
When the elevator starts moving down, the time period increases. But when the elevator is descending at a constant velocity, the time period returns to its normal.
If length of simple pendulem increases constantly during osscillation then what is effct on time period?
If the length of a simple pendulum increases constantly during oscillation, the time period of the pendulum will also increase. This is because the time period of a simple pendulum is directly proportional to the square root of its length. Therefore, as the length increases, the time period will also increase.
What is the relationship between the period of a pendulum and the pendulum length?
The period of a pendulum is directly proportional to the square root of its length. This means that as the pendulum length increases, the period also increases. This relationship is described by the formula T = 2π √(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.
If a runner increases velocity from 2 ms to 4 ms over a period of W seconds what is her acceleration?
Average acceleration over a certain time period is the difference in velocity, divided by the time. In this case, (4-2)/W.
What type of acceleration does a trapezium on a velocity time graph represents?
A period of constant positive acceleration;a second period of zero acceleration; a third period of constant negative acceleration.
Why does speed increase?
Speed increases when a body accelerates under the influence of a force. Newton's second law: acceleration= force/mass. Acceleration is the rate of change of speed over a period of time. For example if you drop an object, it's speed increases by 9.8 meters per second every second.
What is the formula you use to dertermine acceleration?
Acceleration (a) is calculated by dividing the change in velocity (Δv) by the time taken (Δt) over which the change occurs. Mathematically, it can be represented as: a = Δv / Δt. The SI unit of acceleration is meters per second squared (m/s^2).
