Question

A Body start from rest with an acceleration of 2m/s^2. Find the displacement of the body 5 seconds from the start

Answer 1

s= 25 metres
use formula s= ut+ 1/2 at^2
ut will become zero
1/2 at^2= 1/2×2×5×5=25

Answer 2

Gɪᴠᴇɴ :-

• Initial velocity (u) = 0 m/s. --(At rest)
• Acceleration (a) = 2 m/s²
• Time taken (t) = 5 seconds

ᴛᴏ ғɪɴᴅ :-

• Displacement (s)

sᴏʟᴜᴛɪᴏɴ :-

On using second equation of motion , we get,,

➭ s = ut + ½ at²

➭ s = 0×5 + ½ × 2 × (5)²

➭ s = 50/2

➭ s = 25 m

Hence,

• Displacement (s) of body is 25m.
