Question

A train starts from rest and accelerate uniformly at the rate of 5 m/s2 for 5 sec. Calculate the velocity of train in 5 sec.





Answer Right.....:-​

Answer 1

Given

→ Initial velocity (u) = 0

→ Acceleration (a) = 5m/s²

→ time (t) = 5sec

• First equation of motion

→ v = u + at

→ v = 0 + 5 × 5

→ v = 0 + 25

→ v = 25m/s

Answer 2

Answer:

ɪɴɪᴛɪᴀʟ ᴠᴇʟᴏᴄɪᴛʏ =

ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ = ᴍ/s

ᴛɪᴍᴇ = sᴇᴄ

ᴠ=ᴜ+ᴀᴛ

ᴠ=+×

ᴠ=+

ᴠ=ᴍ/s
