(a) Find the velocity at time t. (b) What is the velocity after 1 second? (c) When is the particle at rest? (d) When is the particle moving in the positive direction?
A particle moves according to a law of motion s = f(t), t ≥ …
WebA point particle moves along a straight line such that x= t, where t is time. Then, ratio of acceleration to cube of the velocity is. Medium. View solution. >. The equation of motion of a particle moving along a straight line is s=2t 3− 9t 2+12t, where the units of s and t are centimetre and second. The acceleration of the particle will be ... WebThe original equation describing movement on a line was. s (t) = t³ - 6t² +9t. In this case, there were two times when the particle was speeding up. That would be where the velocity and acceleration are both positive OR both negative in sign. t (1, 2) Time between 1 and 2 seconds. t (3, ∞) Time greater than 3 seconds. bonnie brecht obituary
