When its 115-kW (154.1-hp) engine is generating full power, a small single-engine airplane with mass 685 kg gains altitude at a rate of 3.0 m/s (180 m/min, or 590.4 ft/min). What fraction of the engine power is being used to make the airplane climb? (The remainder is used to overcome the effects of air resistance and of inefficiencies in the propeller and engine.)

the blade of a lawn mower is a 4.25 kg. 74.5 cm long metal (with a shape similar to a meter stick) with a hole at its midpoint. The blade is attached to the engine axle by a bolt through the center hole. when started, the blade accelerates to the full speed at 375 rpm in 5.25 seconds. a) what is the angular acceleration of the blade? b) how fast is blade edge moving 2.55 s after it start? c)...

Boeing 767-400ER model airplane has two engines. Each engine can have a maximum thrust (mechanical force) output of 270 kN. When the plane is cruising at 749.77 km/h, the pilot decides to increase the speed to the typical 850.0 km/h. If drag on the plane is on average 25556 N, and the engines are engaged at 35.21 % of their maximum thrust output, and the plane weighs 128256 kg, how long does it take to reach the new cruising speed?...

to do with friction?
Two blocks are connected by a massless rope that passes over a pulley. The pulley is 12 cm in diameter and has a mass of 2.0 kg. As the pulley turns, friction at the axle exerts a torque of magnitude 0.50 Nm. If the blocks are released from rest, how long does it take uie 4.0-kg block to reach the floor? 4.0 kg 1.0...

A small airplane is flying at a constant altitude with a ground speed of 75 m/s. The pilot needs to reach a point exactly 100 km north of her current location. However, there is a cross wind blowing at 20 m/s in a direction 30 degrees north of east. a. In what direction should the pilot point the plane so that she arrives at her destination as directly as possible. b. How long does it take to complete this part...

3. For Grading Knight 12.64 Flywheels are large, massive wheels used to store energy. They can be spun up slowly, then the wheel's energy can be released quickly to accomplish a task that demands high power. An industrial flywheel has a 1.5 m diameter and a mass of 250 kg. Its maximum angular velocity is 1200 rpm. a. A motor spins up the flywheel with a constant torque of 50 Nm. How long does it take the flywheel to reach...
