If a body moves in a straight line according to the law s = 24t + 3t^2 - t^3, where s is the distance measured in meters from th
Anastasy [175]
As the comments state, the velocity is the derivative of the position.

Therefore, the velocity as function of time is:

ds / dt = 24 + 6t - 3t^2.

That is a parabola whose maximum is (1,27). With that you know that the velocity will never be either 63 m/s or 81 m/s.

Also, you know that the velocity at t = 1 s is 27 m/s.

And, you can also find that the velocity at t = 3 is 15 m/s.

I am confident on that this analysis solves your question. Else, insert a comment.

PtichkaEL [24]
This question was once asked before so I will put it here.

The correct answer for the question that is being presented above is this one: "x = 2; a = 5; b = 3" A 5 inch tall bamboo shoot doubles in height every 3 days. If the equation y=ab^x, where x is the number of doubling periods, represents the height of the bamboo shoot.
