1.) In a local bar, a customer slides an empty beer mug down the counter for The bartender is momentari(c) How far ahead of the target along the x direction should the plane be when it releases the package?ly distracted and does not see the mug, which off the counter and strikes the floor at distance d from the base of the coun height of the counter is h. (Use any variable or symbol stated above along w following as necessary: g.)

(a) With what speed did the mug leave the counter?

(b) What was the direction of the mug's velocity just before it hit the floor?

2.) An airplane flies 200 km due west from city A to city B and then 260 km in the direction of 31.5 north of west from city B to city C.

(a) In straight-line distance, how far is city C from city A?

(b) Relative to city A, in what direction is city C?

3.) An airplane is flying horizontally with a constant velocity of 150 m/s at an altitude of 4600 m when it drops a package.

(a) How long does it take for the package to reach the ground?

(b) What is the distance between the airplane and the package when the package hits the ground? Ignore air resisistance.

c) How far ahead of the target along the x direction should the plane be when it releases the package?

4.) A small map shows Pittsburgh to be 343 miles in a direction 23 north of east from Louisville. The same map shows that Detroit is 209 miles in a direction 48 west of north from Pittsburgh. Assume a flat Earth, and use the given information to find the displacement from Louisville to Detroit.

(a) magnitude: _______ miles

(b) direction: ______ north of east of Louisville

5.) The best leaper in the animal kingdom is the puma, which can jump to a height of 13.1 ft when leaving the ground at an angle of 36. At what speed, in SI units, must the animal leave the ground to reach that height?

What effort have you made to answer the questions? While I am happy to help if you are having difficulties it doesn't do you any good if you if I just tell you the answer. Make some attempt to answer the question and get back to me if you are stuck, explaining why.
