Question

- Find the acceleration (in m/s2 ) of a body which accelerates from 25 m/s to 30 m/s in 10 seconds.

Answer 1

u(initial velocity) =25m/s
v(final velocity) =30m/s
t(time)=10s

a=(v-u)/t
a=(30-25)/10
a=5/10
a=1/2
a=0.5m/s²

Answer 2

Aɴꜱᴡᴇʀ

Acceleration of the body = 0.5 m/s²

✭ Acceleration of a body is given by,

$\large {\underline{ \boxed{ \sf{A = \frac{v - u}{t} }}}}$

❍ Substituting the given values,

$\large \sf \leadsto{}A = \frac{ 30 - 25}{10} \\ \\ \large \sf \leadsto{}A = \cancel\frac{5}{10} \\ \\ \large \sf \pink{\leadsto{}A = 0.5m /{s}^{2}}$
