Question

3) A bus has an acceleration of 10 m/s2
in a straight line. How much velocity is
increased in 10 s?​

Answer 1

Answer:

100 m/s

Explanation:

We know, v = u + at

            or, (v - u) = at

            or, (v - u) = 10 × 10 m/s [(v-u) is the increase in the speed]

                            = 100 m/s

Answer 2

Aɴsᴡᴇʀ:

• The velocity is increased in 10 seconds = 100 m/s

Gɪᴠᴇɴ:

• A bus has an acceleration of 10 m/s2
• in a straight line.

Nᴇᴇᴅ Tᴏ Fɪɴᴅ:

• How much velocity is increased in 10 seconds = ?

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution:

Bʏ ᴜsɪɴɢ ᴛʜᴇ ғɪʀsᴛ ᴇǫᴜᴀᴛɪᴏɴ ᴏғ ᴍᴏᴛɪᴏɴ:

• v = u + at

Pᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇs:

➦ Velocity = 0 + 10 × 10

➦ Velocity = 0 + 100

➦ Velocity = 100 m/s

Tʜᴇʀᴇғᴏʀᴇ:

• The velocity is increased in 10 seconds = 100 m/s
