Answer:
15 m/s
Step-by-step explanation:
Velocity is the derivative of position:
v(t) = s'(t) = 24 +6t -3t^2
v(3) = 24 +3(6 -3·3) = 15
At t=3 seconds, the velocity of the body is 15 m/s.
The answer is 100 because 2 is less than 5.
The answer is 36.
Because 20% of 36 is equal to 7.2
And 36 - 7.2 = 28.80
