An atomic particle moves in a linear motion according to the formula s = 19 - 14t2 + 4t3. Determine the particle's velocity at the end of 2.9 seconds.
velocity in m/s =
My Answer
S'= 0-28t+12t^2
S'(2.9) = 0-28(2.9)+12(
2.9)^2
= 0-81.2+100.92
=19.72
Can you please confirm this answer
velocity in m/s = 19.72
