Question

9. The equation of displacement of any
$s = 9t {}^{3} - 2t {}^{2} + 5t$
object in motion is then
calculate acceleration and velocity after 3 second?​

Answer 1

Answer:

use diffrenciation and u get

v = 27t^2 -4t +5

v at 3s= 236

diffrenciate again

a = 81t -4

a at 3s = 239

Explanation:

hope this helps

sincearly.

random dude

ps just put 3 in place of t and calculate to get answer
