Question

a body initially at rest starts moving with a constant acceleration 2 m/s2 calculate the velocity required and the distance travelled in 5 s

Answer 1

Heya!
--------

-----------------------------------------------------------------------------------------------------

▪Given that ,
=============


⭐Initial Velocity u => 0 [ As the body starts from rest ]

⭐Acceleration a => 2m/s²

⭐Time t = 5 seconds

⭐Final Velocity v = ?

⭐ Distance travelled s = ?


---------------------------------------------------

➡Now using the First Equation of Motion ,


=> V = U + AT

=> V = 0 + 10

=> Final Velocity V => 10 m/s



➡Now using the second Equation of Motion ,

=> S = ut + ½at²

=> S = 0 × 5 + ½ × 2 × ( 5 )²

=> S = 25 m
