eshan29118: they didnt even say that it doesnt come to rest

shashankavsthi: They only asked find KE when force acts on body

gulbibiabro321pcw9jk: Yup this is the right answer thanku

eshan29118: nah after t

shashankavsthi: Force leads to work done and that leads to kinetic energy

shashankavsthi: work done =∆KE

eshan29118: yeah so initially 0 and finally 0

shashankavsthi: How can you say finaly zero ..what if force applied in vaccum!!

eshan29118: well nvm dude ill look into it

shashankavsthi: okay!!
