,2) A block is pulled across a floor as shown in the vector diagram. The greater
component of the vector lies in the
1) horizontal direction,
2) vertical direction,
although both horizontal and vertical components would be of equal magnitude if vector
F were
3) horizontal.
4) vertical.
5) at an angle of 45°.

,Figure V-3
3) The weight of the barrel on the slope is shown by the vector which has components
(not shown) parallel to the surface of the incline and perpendicular to the surface of the
incline. Judging from the slope of incline, the greater of these two components is the one
which is
1) parallel to the slope.
2) perpendicular to the slope.
3) both the same.
4) not enough information is given to say.
If the slope of the incline were steeper, this component vector would
5) decrease.
6) remain the same.
7) increase.
8) again, can't really say.

2) 2
3) 3
4) 4
It is interesting to note that
5) this is the only boat that sails forward.
6) only two of the boats sail forward.
7) three out of the four boats sail forward.
8) all sail forward, but at different speeds.
