Question

Varation Of Displacement (X) Is Described Byx=3-4T-5T^2-6T^3 Find Initial Velocity

Answer 1

Answer:

See below.

Explanation:

Displacement ( x ) is given as a function of time ( t ) as,

$f( t ) = 3 - 4t - 5t^2 - 6t^3$

To find the velocity, we need to calculate the derivative of the displacement with respect to time like,

$v = \frac{d x}{d t} = -4 - 10t - 12t^2$

We can write this as function g,

$v = g( t ) = -4 - 10t - 12t^2$

Plug the value of t and you will get the velocity attained at that instance of time.
