Qᴜᴇsᴛɪᴏɴ :-

ᴀ ᴄᴀʀ sᴛᴀʀᴛs ᴛᴏ ᴍᴏᴠᴇ ғʀᴏᴍ ʀᴇsᴛ. ɪғ ᴀғᴛᴇʀ 10 sᴇᴄᴏɴᴅs ɪᴛ’s ᴠᴇʟᴏᴄɪᴛʏ ɪs 20 ᴍ/s2 ғɪɴᴅ ɪᴛs ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ.

Sᴏʟᴜᴛɪᴏɴ :-

ᴜ ( ɪɴɪᴛɪᴀʟ ᴠᴇʟᴏᴄɪᴛʏ) = 0 ᴍ/s ( ʙᴇᴄᴀᴜsᴇ ʙᴏᴅʏ sᴛᴀʀᴛs ғʀᴏᴍ ʀᴇsᴛ)

ᴠ ( ғɪɴᴀʟ ᴠᴇʟᴏᴄɪᴛʏ) = 20 ᴍ/s

Tɪᴍᴇ = 10 sᴇᴄᴏɴᴅs

ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ =(ᴠ - ᴜ) /ᴛɪᴍᴇ

➡ =(20 - 0 )/10

➡ = 20 /10

➡ = 2 ᴍ/s^2

Hᴇɴᴄᴇ,

Tʜᴇ ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ ɪs 2 ᴍ /s^2.
