d most silly q

a,b,c kyun diye hain

please write the equation

Mata ji yahan par

A particle is moving along x-axis as_______________________ ; where x is in m, t in second, a = 1; b =- 3, c = 2, distance cover by particle from t = 1 to t = 2,
(A) 0.5 m (B) zero
(C) 2 m (D) None

Fill in the blank to kar do

Ans a????

dunno post d sol ............... really itz bettr then zer o :D

method:

find where velcity becomes zero

at t=3/2s

find x at t=3/2

and find 2x

can u xplain in wrds .i mean wats d logic behind this

sorry if m being dumb

initially at t=1 x=0

at t=2 also x=0

so it has returned to its initial position. Now if it returns velocity has to become zero at some point before it changes direction. so find v=dx/dt and put v=0

I know ive explained clumsily. Say if you can get or ill post again
