Given ,
x = 32t- 8t^2/3
differentiating on bothsides with respect to t
dx/dt = 32- (8/3)2t
dx/dt = 32- 16t/3
Again differentiating w.r.t t
or , d^2x/dt^2 = -16/3
= -5.33
i.e acceleration = -5.33 m/s2
x = 32t- 8t^2/3
differentiating on bothsides with respect to t
dx/dt = 32- (8/3)2t
dx/dt = 32- 16t/3
Again differentiating w.r.t t
or , d^2x/dt^2 = -16/3
= -5.33
i.e acceleration = -5.33 m/s2
but the answer is -32m
i am amazed .Why everyone depends upon book? .It is clear that answer is -5.33..32 is already cancelled on first differentiation .Believe on you .And ask other too if you are not believing on this answer.
srry i dont know
anyways thanks
