Given :

  • Initial velocity (u) = 0 m/s

  • Final velocity (v) = 40 m/s

  • Time (t) = 5 seconds

To Find :

  • Acceleration = ?

Solution :

v = u + at -----(First equation of motion)

➨ 40 m/s = 0 + a × 5 s

➨ a = 40/5

a = 8 m/s²

Therefore, the acceleration of the body is 8 m/s².

Given :

Initial velocity,u = 0

Final velocity,v = 40m/s

time ,t = 5 sec

Required To Find out :

Acceleration

Formula required :

\large{\red{V=U+AT}}

where ,

v is final velocity

u is initial velocity

a is acceleration produced

t is the time taken

Solution :

v = u + at \\ 40 = 0 + a \times 5 \\ 40 = 5a \implies \: a =  \frac{40}{5}  \\  \implies \: a = 8 m{s}^{ - 2}

hence, the acceleration produced is 8m/s^2
