Question

The displacement of a particle is given by S=2 t square + 3t + 2 it's displacement after 4 seconds is​

Answer 1

Answer:

dx/dt = 0 (given)

So,

8t-8=0, t=1sec.

Now, x=4 (1×1) -8(1)=-4m

So, displacement is in negative direction

Explanation:

dx/dt = 0 (given)

So,

8t-8=0, t=1sec.

Now, x=4 (1×1) -8(1)=-4m

So, displacement is in negative direction
