Q. An object travels along a straight line. The function

v(t) = 5\cos t - 4t

gives the object's velocity, in feet per hour, at time

t

hours.

\newline

Write a function that gives the object's acceleration

a(t)

in feet per hour per hour.

\newline

a(t) = ______

Identify Velocity Function: Identify the velocity function and recognize the need to differentiate it to find acceleration.
Differentiate Velocity Function: Differentiate each term of the velocity function to find the acceleration function.
Combine Derivatives for Acceleration: Combine the derivatives to form the acceleration function.
