ɢɪᴠᴇɴ :-

  • Initial velocity (u) = 0 m/s
  • Final velocity (v) = 4m/s
  • Time taken (t) = 4 seconds

ᴛᴏ ғɪɴᴅ :-

  • Acceleration (a)

sᴏʟᴜᴛɪᴏɴ :-

On using 1st equation of motion, we get,.

v = u + at

4 = 0 + a×4

4a = 4

a = 4/4

a = 1 m/s²

Hence,

  • Acceleration (a) = 1 m/s²

Given,

  • A body starts from rest and Travel at 4 m/s (Final Velocity)
  • Initial Velocity - 0 m/s ( Because body start from rest)
  • Time - 4 Seconds

To Find,

  • Acceleration of the Body

Solution :

\longrightarrow We know about the First Equation of Motion :

\bigstar \boxed{\mathfrak{v = u + at}}

Here,

  • v - Final Velocity
  • u - Initial Velocity
  • t - Time
  • a - Acceleration

Now Put the Value in this Equation :

\longmapsto \sf{v = u + at}

\longmapsto \sf{4 = 0 + a \times 4}

\longmapsto \sf{4 = 4a}

\longmapsto \sf{a = \dfrac{4}{4}}

\longmapsto \boxed{\sf{a = 1\:m/s^{2}}}

Therefore,

\underline{\boxed{\red{\mathfrak{Acceleration\:of\:the\:Body - 1\:m/s^{2}}}}}
