Mark the correct alternative in the following: If s = t 3 – 4t 2 + 5 describes the motion of a particle, then its velocity when the acceleration vanishes, is

Question

Philoid · Accepted Answer

If we are given the distance travelled(s) as a function of time, we can calculate velocity(v) and acceleration(a) by

and a

s(t)= t³ – 4t² + 5

differentiating w.r.t. time, we get

Differentiating again w.r.t. time, we get

a

Given that a=0 ⇒ 6t-8=0 or units
