Akagi was a Japanese aircraft carrier used during World War II. The upper flight deck sloped slightly fromamidships toward the bow and toward the stern to assist landings and takeoffs for the underpowered aircraft of that time. Assumea 5 m drop from amidship to the bow. Assume the Japanese Nakajima Ki‐84 plane could takeoff in a length of about 58 m at a speedof 31 m/s. The mass of the plane is 3600 kg fully loaded with gasoline. What force is the engine required to produce for takeoff?Ifthe deck were not sloped, what force would the engines require for takeoff?

A 0.50-kg block slides across a table top with an initial speed of 20 cm/s and comes to rest on a distance of 70 cm. Find the average friction force that retarded its motion.

A 3 kg block sits on a level table and a string runs over the edge of the table on a pulley to a mass of 10 kg. Find the velocity of the hanging mass after 5 seconds if it starts at rest and if the coefficient of friction is 0.7.
