A body of mass 6 kg is acted upon by a forcewhich causes a displacemen

1.	A body of mass 6 kg is acted upon by a forcewhich causes a displacement in it given by xmetre where t is the time in second. Thework done by the force in 2 s is(1) 12J (2) 9J (3) 6J (4) 3 J
Answer» answer is 3J option d but why???? is it correct? yahh tell me why first find acc. by differentiating displacement two times then find force =m×a then displacement in 2 seconds is of 1m then multiply force and displacement to get work done plz solve it & send me pic mera ans. tele nahi ho rha bro i am solving the question which u gave before let me solve it I will send sol for both k or u will send it in my phone no. is 9409647647 as it is my parent's phone if u can do whatssapp sorry bro i will be sending here only and dont share ur no.its a public place k and another one?

answer is 3J option d

but why????

is it correct?

yahh

tell me why

first find acc. by differentiating displacement two times then find force =m×a then displacement in 2 seconds is of 1m then multiply force and displacement to get work done

plz solve it & send me pic

mera ans. tele nahi ho rha

bro i am solving the question which u gave before let me solve it I will send sol for both

or u will send it in my phone no. is 9409647647 as it is my parent's phone

if u can do whatssapp

sorry bro i will be sending here only and dont share ur no.its a public place

and another one?
