Question

. A body starts from rest with a uniform acceleration 2 m/s². Find the distance covered by the

body in 2 s​

Answer 1

Gɪᴠᴇɴ :-

Initial velocity (u) = 0 m/s. --(At rest)

Acceleration (a) = 2 m/s²

Time taken (t) = 2 seconds

ᴛᴏ ғɪɴᴅ :-

Distance travelled (s)

sᴏʟᴜᴛɪᴏɴ :-

Now,

On using second equation of motion, we get,

➭ s = ut + ½ at²

➭ s = 0×2 + ½ × 2 × (2)²

➭ s = 8/2

➭ s = 4 m

Hence,

Distance travelled (s) is 4 m

Answer 2

Answer:

ok

likes my All ans

thank you

Explanation:

u =0, a=2m/s2

,t=2s

Putting the values in S=ut+ 1/2 at²

S=0×2+ 1/2 ×2×2²

S=4m
