How does multiplying a vector by a scalar value of 2π change the vector?
The vector will not change direction but will increase in magnitude.
A 5-lb. force acting in the direction of <5, -3> moves an object just over 12 ft. from point (0, 6) to
(7, -4). Find the work done to move the object to the nearest foot-pound.
56 ft.·lbs.
Find the component form of -u - v given that u = <-5, 6> and v = <7, -3>.
<-2, -3>
For v = -4i - 5j, find unit vector u in the direction of v, and write your answer as a linear
combination of the standard unit vectors i and j.
u = -((4sqrt(41))/(41))i - -((5sqrt(41))/(41))j
Find u * v, if u = 14j and v = i + 4j.
