The velocity of a particle moving along the x axis is given by vx = a t − b t3 for t > 0 , where a = 26 m/s 2 , b = 1.4 m/s 4 , and t is in s. What is the acceleration of the particle when it achieves its maximum displacement in the positive x direction?

-52 m/s²

Explanation:

Velocity is given by

Acceleration is given by

For maximum displacement we have to equate v = 0

Substituting in the acceleration equation

The acceleration when maximum displacement is achieved is -52 m/s²

answer: 0.20

explanation: this can only be the answew because all the other measuremnets are not close

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
