Question

A car accelerate uniformly from 18km /h to 36km/h in 5sec calculate the acceleration

Answer 1

18km/h=5m/s and 36km/h=10m/s

initial velocity =5

and final velocity = 10

a=v-u/t

u=10 and v =5 t=5

10-5/5 =1m/s^2

Answer 2

GiveN :-

• Initial velocity = 18 km/h = 5 m/s

• Final velocity = 36 km/h = 10 m/s

• Time = 5 s

To FinD :-

• Acceleration of the car

SolutioN :-

Acceleration of the car is :

$\large\longrightarrow \boxed{ \red{\bf Acceleration = \frac{v - u}{t}}} \\ \\ \longrightarrow \sf a = \frac{10 - 5}{5} \\ \\ \longrightarrow \sf a = \frac{5}{5} \\ \\ \longrightarrow \underline{\boxed{ \sf a = 1 \: {ms}^{ - 2}} }$

$\large \therefore\: \underline{ \blue{ \bf Acceleration\: of \:car \: is\: 5\:{ms}^{ - 2}}}$
