Question

A body moving with a velocity of 2m/s acquires a velocity of 10m/s in 5sec find its acceleration

Answer 1

Answer:

Explanation:

initial velocity=2 m/s

final velocity=10 m/s

time taken=5 sec

acceleration=v-u/t

a=10-2/5

 =1.6 m/s²

hope it helped and pls mark as brainliest:)

Answer 2

Given :

• Initial Velocity (u) = 2m/s
• Final Velocity (v) = 10m/s
• Time Taken (t) = 5 sec.

To Find :

• Acceleration (a) of the body.

Solution :

$\longmapsto\tt{Acceleration(a)=?}$

Using 1st Equation of Motion :

$\longmapsto\tt{v=u+at}$

Putting Values :

$\longmapsto\tt{10=2+a(5)}$

$\longmapsto\tt{10-2=5a}$

$\longmapsto\tt{8=5a}$

$\longmapsto\tt{a=\cancel\dfrac{8}{5}}$

$\longmapsto\tt\bold{a=1.6{m/s}^{2}}$

So , The acceleration of the body is 1.6 m/s²..
