Question

an object moving with velocity of 20m/s and suddenly increase the velocity up to 40m/s in just 5 seconds. Calculate accerleration.

Answer 1

Answer:

Acceleration= 4m/s^2

Explanation:

$\tt \huge \red{༒︎To \: \: Fɪɴᴅ:-}$

• Acceleration ( a )

$\tt \huge \red{༒︎Given:-}$

• Initial velocity of object = 20m/s ( u )

• Final velocity = 40m/s ( v )

• Time = 5 seconds ( t )

$\tt \huge \red{༒︎ Formula:-}$

$\tt Acceleration ( a ) = \frac{ \: v \: - \: u}{t}$

☞︎︎︎Nᴏᴡ ᴘᴜᴛ ᴛʜᴇ ᴠᴀʟᴜᴇ ɪɴ ғᴏʀᴍᴜʟᴀ,

$\to \tt a = \frac{40 - 20}{5} \\ \tt \to a = \frac{20}{5} \: \: m {s}^{ - 2} \\ \tt \to a = 4 \frac{m}{ {s}^{2} } \: \: or \: \: 4m {s}^{ - 2}$
