Question

The height of an object at time t is given by  . Determine the object's velocity at t = 4.
A) 130 
B) -136 
C) -130 
D) -66

Quizplus · Accepted Answer

To find the velocity, we need to take the derivative of the height function with respect to time:

v(t) = 44t^2 - 352t + 528

Plugging in t = 4, we get:

v(4) = 44(4)^2 - 352(4) + 528 = -130

Therefore, the correct answer is (C) -130.
