Question

A body moving with a constant acceleration has its velocity changed by 10 ms in 5s. What is the value of acceleration​

Answer 1

Answer:

2 m/s²

Explanation:

Given:

Time = 5 seconds (t)

As 10 m/s is the change in the velocity it can be written as (final velocity-initial velocity) (v-u)

To find:

acceleration (a)

We know that a = $\frac{v-u}{t}$

where,

a =  acceleration

v = final velocity

u =  initial velocity

t = time

Substituting the values, we get:

a = $\frac{10}{5}$

a = 2 m/s²

The acceleration of the body is equal to 2 m/s²

Answer 2

AnswEr:

$\sf{\blue{Accelaration\:=\:2\:m/s^2}}$

ExplanaTion:

Given that,

• (v - u) = 10 m/s

• t = 5 s

To find :

• Accelaration.

SoluTion :

We know that,

$\large{\boxed{\sf{\red{a\:=\:\dfrac{(v - u)}{t}}}}}$

$\sf{Where}$ $\begin{cases}\sf{v\:is\:final\:velocity}\\\sf{u\:is\:initial\:velocity}\\\sf{t\:is\:time\:taken}\\\sf{a\:is\:accelaration}\end{cases}$

Putting the given values,

$\longrightarrow$ $\sf{a\:=\: \dfrac{10}{2}}$

$\longrightarrow$ $\sf{\red{a\:=\:2\:m/s^2}}$

Hence, accelaration is 2 m/s²

★ What is accelaration?

→ The rate of change of velocity is called as accelaration.

→ S.I unit of accelaration is meter per second squares.

→ It is a vector quantity i.e having both magnitude as well as direction.
