Question

Find the acceleration of a car which changes its velocity from 10m/s to 20m/s in one minute.
( Hint : accelaration = v-u/t )

For correct answer I will mark as brainliest.​

Answer 1

Given :

• Initial velocity of the car = 10 m/s
• Final velocity of the car = 20 m/s
• Time = 1 minute

To Find :

• The acceleration of the car

Solution :

Using the formula ,

$\\ \star \: {\boxed{\purple{\sf{a = \frac{v - u}{t} }}}}$

Where ,

• a is acceleration
• v is final velocity
• u is initial velocity

We have ,

• v = 20 m/s
• u = 10 m/s
• t = 1 minute = 60 sec

Substituting the values in the formula ,

$\\ : \implies \sf \: a = \frac{20 - 10}{60}$

$\\ : \implies \sf \: a = \frac{10}{60}$

$\\ : \implies \sf \: a = \frac{1}{6}$

$\\ : \implies{\underline{\boxed{\pink{\mathfrak{ a = 0.16 \: m {s}^{ - 2} }}}}} \: \bigstar$

$\\ \therefore{\underline{\sf{Hence \: , \: The \: acceleration \: of \: the \: car \: is \: \bold{0.16 \: ms^{-2}}}}}$

Answer 2

Initial velocity : 10 m/s

New Velocity: 20m/s

Time Taken : 60 sec

acceleration = Initial Velocity - new Velocity / Time taken

10-20 / 60

10 / 60

acceleration= 1/6 m/s
