Question

find the acceleration if initial velocity is 10 m/s and final velocity 18m/s and the time is 2 seconds​

Answer 1

Given:-

• initial velocity = 10m/s
• final velocity = 18m/s
• time = 2 seconds

To find:-

• acceleration

Formula:-

$\underline{\boxed{\sf Acceleration = \dfrac{final\: velocity-initial\: velocity}{time}}}$

Solution:-

$\implies$ $\sf acceleration = \dfrac{18-10}{2}$

$\implies$ $\sf acceleration = \dfrac{8}{2}$

$\implies$ $\sf acceleration = 4m/s²$

Additional information:-

• 1st equation of motion:-

$\implies$ $\underline{\boxed{\sf v = u+at}}$

here,

• v = final velocity
• u = initial velocity
• a = acceleration
• t = time

_________

• 2nd equation of motion

$\implies$ $\underline{\boxed{\sf S = ut+\dfrac{1}{2}at²}}$

here,

• s = distance
• u = initial velocity
• t = time taken
• a = acceleration

___________

• 3rd equation of motion

$\implies$ $\underline{\boxed{\sf v²-u² = 2as}}$

here,

• v = final velocity
• y = initial velocity
• a = Acceleration
• s = distance
