Question

If a car is moving with a velocity 10m/s and reaches its. the velocity 50m/s in 4sec then find the acceleration of the car?

Answer 1

Answer:

a = 10m/sec^2

Explanation:

a = v-u/t

v = 50m/sec

u = 10m/sec

a = 50 - 10 /4

a = 40/4

a = 10m/sec^2

Answer 2

Given :

➾ Initial velocity = 10m/s

➾ Final velocity = 50m/s

➾ Time interval = 4s

To Find :

⟶ Acceleration of car.

SoluTion :

➠ Acceleration is defined as the rate of change of velocity.

➠ It is a vector quantity having both magnitude as well as direction.

➠ It can be positive, negative or zero.

➠ SI unit : m/s²

✴ First equation of kinematics :

$\bigstar\:\underline{\boxed{\bf{v=u+at}}}$

• v denotes final velocity
• u denotes initial velocity
• a denotes acceleration
• t denites time

$\dashrightarrow\tt\:v=u+at$

$\dashrightarrow\tt\:a=\dfrac{v-u}{t}$

$\dashrightarrow\tt\:a=\dfrac{50-10}{4}$

$\dashrightarrow\tt\:a=\dfrac{40}{4}$

$\dashrightarrow\underline{\boxed{\orange{\bf{a=10\:ms^{-2}}}}}\:\gray{\bigstar}$
