# Three forces of magnitudes f1=4.0n, f2=6.0n, and f3=8.0n are applied to a block of mass m=2.0kg, initially at rest, at angles shown on the diagram. (figure 1) in this problem, you will determine the resultant (net) force by combining the three individual force vectors. all angles should be measured counterclockwise from the positive x axis (i.

e., all angles are positive). None

# A periscope. is useful for viewing objects that cannot be seen directly. It can be used in submarines and when watching golf matches or parades from behind a crowd of people. Suppose the object is a distance p1 from the upper mirror and the centers of the two flat mirrors are separated by a distance h.

(a) What is the distance of the final image from the lower mirror? (Use any variable or symbol stated above as necessary.) d =___________ behind the lower mirror (b) What is its magnification? None

# University of Florida football programs are printed 1 week prior to each home game. Attendance averages 75 comma 000 screaming and loyal Gators​ fans, of whom​ two-thirds usually buy the​ program, following a normal​ distribution, for ​\$5 each. Unsold programs are sent to a recycling center that pays only 10 cents per program. The standard deviation is 10 comma 000 ​programs, and the cost to print each program is ​\$2. Refer to the standard normal tableLOADING... for​ z-values.

(a) What is the cost of underestimating demand for each program? (b) What is the overage cost per program? (c) How many programs should be ordered per game? (d) What is the stockout risk for this order size? None
