Question

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

Answer 1

Answer:

10 m/s square

Explanation:

initial(u)=10m/s

final(v)=50m/s

time(t)=4sec

we have to find aceleration so we can use first equation of motion.

(v=u+at)

50=10+4a

50-10=4a

40=4a

40/4=a

a=10m/s square =Ans

Answer 2

$\;\;\underline{\textbf{\textsf{ Given:-}}}$

• Initial Velocity, u = 10m/s

• Final Velocity, v = 50m/s

• Time Taken, t = 4sec

$\;\;\underline{\textbf{\textsf{ To Find :-}}}$

• Acceleration (a)of the car.

$\;\;\underline{\textbf{\textsf{ Solution :-}}}$

$\underline{\:\textsf{Let's try to know about density :}}$

• It is defined as the rate of change of velocity of the object.

$\underline{\:\textsf{ Formula :}}$

$\tt{\large{\boxed{\bold{\bold{\green{\sf{Acceleration=\dfrac{v-u}{t}}}}}}}}$

$\underline{\:\textsf{ Now, put the given values in the formula :}}$

$\longrightarrow\tt{\dfrac{50-10}{4}}$

$\longrightarrow\tt{\cancel\dfrac{40}{4}}$

$\longrightarrow\tt\bold{{10m/s}^{2}}$

$\;\;\underline{\textbf{\textsf{ Hence-}}}$

$\underline{\textsf{ The Acceleration of the car is \textbf{10m/s² }}}.$
