The v2 - x graph is given for a particle undergoing a straight line
motion. The acceleration of the particle is:
(Ay 2i m/s2
(B) 1i m/s2
(C) -1/2 îm/s2
(D) -1i m/s2​

Answer 1

Answer:

B) 1i m/s2

Explanation:

V2=2

V= under root 2(here I am writing root2 as 2^1/2

U=0

S=1

V=u +at

2^1/2=0+at

2^1/2=at - - - - - 1

S=ut +1/2at^2

1=0(t)+1/2at^2

1=1/2at×t

Substituting - - 1

We get

2=2^1/2×t

t=2^1/2

V=u +at

2^1/2=at

2^1/2=a×2^1/2

a=1i m/s^2
