Question

Car starting from rest moves with uniform acceleration if 2m/s for 10s find the distance travelled by car

Answer 1

Explanation:

S=ut +1/2at^2

S=0+1/2*2*100

S=100 m

Answer 2

❥︎ ɪɴɪᴛɪᴀʟ ᴠᴇʟᴏᴄɪᴛʏ =ᴜ = 0ᴍ/sᴇᴄ

❥︎ ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ = ᴀ= 2ᴍ/sᴇᴄ²

❥︎ ᴛɪᴍᴇ = ᴛ = 10sᴇᴄ

❥︎ ᴅɪsᴛᴀɴᴄᴇ = s = ?

ʙʏ 2ɴᴅ ᴋɪɴᴇᴍᴀᴛɪᴄᴀʟ ᴇǫᴜᴀᴛɪᴏɴ...

s = ᴜᴛ + (1/2) ᴀᴛ²

s= 0 + (1/2) (2)(10)²

s = 100 ᴍᴇᴛʀᴇs (ᴅɪsᴛᴀɴᴄᴇ)

NOTE:-

• ᴛʜɪs ᴇǫᴜᴀᴛɪᴏɴ ɪs ᴏɴʟʏ ᴠᴀʟɪᴅ ᴡʜᴇɴ ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ ɪs ᴄᴏɴsᴛᴀɴᴛ.

• 1sᴛ ᴋɪɴᴇᴍᴀᴛɪᴄᴀʟ ᴇǫᴜᴀᴛɪᴏɴ ɪs [ᴠ=ᴜ+ᴀᴛ]

• 3ʀᴅ ᴋɪɴᴇᴍᴀᴛɪᴄᴀʟ ᴇǫᴜᴀᴛɪᴏɴ ɪs [ ᴠ²= ᴜ² + 2ᴀs]

hope it helps......
