Question

A body starts from rest and is found to cover 3m during the5 second of it's motion find acceleration

Answer 1

Given conditions ⇒

A body is starts at the rest,

∴ Initial Velocity of the body (u) = 0

Now, Distance covered b the body = 3 m.

Time taken by the body = 5 seconds.

∴ Velocity of the body = Distance/Time

= 3/5

= 0.6 m/s.

∴ Final Velocity (v) of the body = 0.6 m/s.

Now, Using the Formula,

 

∴  

∴  

∴ a = 0.12 m/s².

Hence, the acceleration of the body is 0.12 m/s².

Hope it helps.
