Kinematics involves the study of vector quantities of position, velocity, and acceleration as a function of time. Which of the vector-properties of position, velocity, and acceleration can change with time?
Magnitude only
Direction only
Both direction and magnitude
Neither direction nor magnitude since both are constant with time for kinematics problems.

Suppose you have two time-dependent (t)
Which of the following represents the first time derivative of A dot B?
Suppose you have two time-dependent (t) vectors A and B where A(t) = (5t)i + (t2)j and B(t) = (2t)i + j, where i and j are unit vectors in the x- and y-directions, respectively.
Which of the following represents the first time derivative of A dot B?
22t
10t2 +25t + 5
2t4 + 6t2 - 8
