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

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

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

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

Given two vectors A =  -3 i + 4 j   and B = 4 i – 3 j  . Let  C = A x B . Which direction does C point to?

You throw a ball vertically upward from the roof of a building.  The ball leaves your hand at even with the roof railing with an upward speed of m/s; the ball is then in free fall. On the way back down, it just misses the railing and hits the ground s after it leavs your hand.  How tall is the building?

A boy throws a rock with an initial velocity of m/s at degrees above the horizontal.  If air resistance is negligible, how long does it take for the rock to reach the maximum height of its trajectory?
