Answer:

$\huge\mathfrak\red{\bold{\underline{☯︎{Lεศɢนε \: σʄ \: Mıŋɖร}☯︎ }}}$

$\huge\fbox\red{Given:}$

• Velocity of a car started from rest reaches 24 m/s in 4 seconds.

$\huge\fbox\red{To find:}$

• Acceleration of the car.

$\huge\underbrace\mathscr\color{lime}{ †\: Solution:–}$

$\huge\longrightarrow$Initial Velocity = 0 m/s

$\huge\longrightarrow$Final Velocity 24 m/s

$\huge\longrightarrow$ Taken 4 seconds

$\fbox\green{Using\:1st\: equation:}$

• v = u + at

Putting Values :

$\large\implies$ 24 = 0+ a(4)

$\large\implies$ 24 = 0 + 4a

$\large\implies$ 24 = 4a

$\large\implies$ 24 = 4a

$\large\implies$ $a = \cancel \frac{24} {4}$

$\large\implies$ a = 6 m/s

So, The Acceleration of the car is 6 m/s.

Three Equations Of Motion :

• v = u+ at

• S = ut + 1/2 at

• v² - u² = 2as

Here:

• v = Final Velocity

• u = Initial Velocity

• t = Time Taken

• a = Acceleration

• s = Distance Travelled

Answer 2

Velocity of a car started from rest reaches 24

To find:

Acceleration of the car.

Solution:–

 Initial Velocity = 0 m/s

 Final Velocity 24 m/s

Taken 4 seconds

Using 1st equation:

v = u + at

Putting Values :

⟹ 24 = 0+ a(4)

⟹ 24 = 0 + 4a

⟹ 24 = 4a

⟹ 24 = 4a

⟹ a=424

a= 6m/s

So, The Acceleration of the car is 6 m/s.

Three Equations Of Motion :

v = u+ at

S = ut + 1/2 at

v² - u² = 2as

Here:

v = Final Velocity

u = Initial Velocity

t = Time Taken

a = Acceleration

s= distance travelled
