Question

What is the kinetic energy of 60 kg mass moving with a velocity 40 m/s?

Answer 1

ɢɪᴠᴇɴ ..

• ᴍᴀss ᴏғ ᴀ ʙᴏᴅʏ = 60 ᴋɢ

• ᴠᴇʟᴏᴄɪᴛʏ ᴏғ ᴀ ʙᴏᴅʏ = 40ᴍ/s

ғᴏʀᴍᴜʟᴀ ᴜsᴇᴅ :-

ᴋ.ᴇ.$= \frac{1}{2} m {v}^{2}$

sᴏʟᴜᴛɪᴏɴ :-

ᴋᴇ =

$</strong><strong> \frac{1}{2} \times 60 \times {40}^{2} \\ \: \: \: = 30 \times1600 \\ \: \: \: = 48000</strong><strong> </strong><strong>$
