Which formula is used to find an objects acceleration

irina [24]

Answer:

a=∆v/∆t

Explanation:

The definition of Acceleration is the change in velocity in a given time. So this means you first calculate ∆v (Change in velocity), and you calculate ∆t which is the time taken to apply that change in velocity. Then you find a= ∆v/∆t. This gives us the equation of Acceleration.

A bird is flying to the right when a gust of wind causes the bird to accelerate leftward at 0.5\,\dfrac{\text m}{\text s^2}0.5 s

Licemer1 [7]

The initial velocity of the bird before the gust of wind : <u>4 m/s</u>

<h3>Further explanation</h3>

An equation of uniformly accelerated motion

$\large {\boxed {\bold {x = xo + vo.t + \frac {1} {2} at ^ 2}}}$

v = vo + at

Vt² = vo² + 2a (x-xo)

x = distance on t

vo/vi = initial speed

vt/vf = speed on t /final speed

a = acceleration

Acceleration is a change in speed within a certain time interval

a = Δv /Δ t

$\displaystyle a=\frac{v2-v1}{t2-t1}$

Let complete the task :

A bird is flying to the right when a gust of wind causes the bird to accelerate leftward at 0.5 m/s² for 3 s. After the wind stops, the bird is flying to the right with a velocity of 2.5 m/s.

Assuming the acceleration from the wind is constant, what was the initial velocity of the bird before the gust of wind?

we can use formula :

vf = vi + a.t

vf = final velocity = 2.5 m/s

vi = asked

a = - 0.5 m/s²(leftward=negative)

t = 3 s

then :

$\displaystyle 2.5=vi-0.5.3\\\\vi=2.5+1.5\\\\vi=\boxed{\bold{4\frac{m}{s}}}$
