A cheetah is couched [a] m to the east of a vehicle.  At time t=0 it begins to runs along a straight line due east.  The cheetah’s x-coordinate varies with time according to the equation x(t) = [a] m + ([b] m/s2)t2 + ([c] m/s3)t3. Find the cheetah’s average velocity between t1 = [t1]s and t2=[t2].

There are two non-zero vectors A and B. Under what condition is |A – B| = A + B ?

Ryan & Patrick (2001) studied four dimensions of the classroom social environment that they believe influence feeing of relatedness in a middle school classroom. Name and define each and offer an example of how you might employ each in your classroom as a teacher. (Please number each item)

Vector A , on the x-y plane, has a magnitude of [a] unit and points in the direction of [angle] degrees measured counterclockwise direction from +x axis. Vector B has components of Bx= [bx], By = [by], Bz= [bz].  Find their dot product A • B ?   

The position of an object is given by x=([A] m/s3)t3 + ([B] m/s2)t2 +([C] m/s)t + [D] m/s. What is the instantaneous acceleration (in m/s2) of the object when t=[t] s?  

A child runs off a [h]-m high dock horizontally and splashes into pond water at a distance [x]-m from the bottom edge of the dock. Find the speed she runs off the dock.

Vector A has magnitude [A], and vector B has magnitude [B].  The angle between them is [AngleDeg] degrees. What is the magnitude of product A x B ?
