Question

a body is moving with a velocity of 12 m per second and it comes to rest in 18 M what was the acceleration

Answer 1

hope u like it brother



bro and v=final velocity

u=intial velocity

Answer 2

Hey there

• Given :-

Initial velocity , u = 12 m/s

final velocity , v = 0 m/s { it comes to rest }

time , t = 18 m or = 18 × 60 s

we know ,

$\boxed{ \bf v = u + at => a = \frac{v - u}{t} }$
putting the value we obtain

$\bf a = \frac{ - 12}{18 \times 60} = > a = \frac{ -1}{3 \times30 } = \frac{ - 1}{90} = - 0.01 {ms}^{ - 2}$


Hope this helps you ☺
