From the veranda of a beachfront hotel, Manny is searching the seascape through his binoculars. A ship suddenly appears on the horizon. If Manny is 80ft above the earth, how far is the ship out at sea? HINT: See Exercise 27 and note that 1mi=5280ft. An airplane reaches an altitude of 3mi above the earth. Assuming a clear day and that a passenger has binoculars, how far can the passengers see? HINT: The radius of the earth is approximately 4000 mi.

A wrench 25 cm long lies along the positive y-axis and grips a bolt at the origin. A force is applied in the direction (a.3.-4) at the end of the wrench. Find the magnitude of the force needed to supply 100 N · m of torque to the bolt. (Round your answer to the nearest whole number.)

A 50 N force is applied at the end of a 20 cm wrench and makes an angle of 30° with the handle of the wrench. Find the magnitude of the torque. b. What is the maximum torque that can be exerted by a 50 N force on the wrench and а. how it can be achieved?

L 21. A mason is building a square based column similar in shape to the Washington Monument, to border a drive way. It is 48 inches wide at the base and tapers 88 degrees.
