Question

A bus starting from rest moves with a uniform acceleration of 0.1m/s2 for 2 minutes. Find the speed acquired

Answer 1

Answer:

o.2m/s2

Explanation:

we know that

v=u+at

and it is given that initial velocity is zero because a bus starting from rest and acceleration(a) is also given and time is also given 2 min

therefore,put all given values in v=u+at we get 0.2m/s2

Answer 2

Aɴsᴡᴇʀ:

• The speed acquired = 12 m/s

Gɪᴠᴇɴ:

• A bus starting from rest moves with a uniform acceleration of 0.1m/s2 for 2 minutes.

Nᴇᴇᴅ ᴛᴏ ғɪɴᴅ:

• The speed acquired = ?

Solution:

Convert unit here:

1 min = 60 seconds

2 min = 2 × 60

2 min = 120 seconds

Bʏ ᴜsɪɴɢ ᴛʜᴇ ғɪʀsᴛ ᴇǫᴜᴀᴛᴏɴ ᴏғ ᴍᴏᴛɪᴏɴ:

• v = u + at

Pᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇs:

➦ Required velocity = 0 + 0.1 × 120

➦ Required velocity = 0 + 120

➦ Required velocity = 12 m/s

Tʜᴇʀᴇғᴏʀᴇ:

• The speed acquired is 12 m/s.
