1. A Cessna 206H has a mass of 1000 Kg, a takeoff speed of 34 m/s (about 67 kn) and its propeller generates a power of 224 KW (224 kilowatts or 300 hp). Assuming no air drag and full, constant power, calculate the time it takes the Cessna to reach the takeoff speed.
2. Calculate the Kinetic Energy KE and the Angular Momentum L of a rigid object with a moment of inertia 0.4 Kgm2 spinning around a fixed axis with angular speed 10 rad/s.
3. An 8 Kg box is pulled 20 m up along a 30° incline plane by an applied force of 100 N that points upwards, parallel to the incline. If friction is negligible, calculate the total work done on that box.
4. A block with a mass of 2.00 kg is attached to a horizontal spring with spring constant k = 400 N/m. The block is pulled out to 0.080 m, released with no initial speed, and it comes to a temporary stop 0.060 m on the opposite side. Calculate the work done by friction force.

The 30 kg mass has a speed of 2m/sec in the position shown and a constant force of 20N is applied on it as shown and this force is acting on the mass for another 3 meters down the incline and then disappears. After another 7 meters the mass hits a loss of energy at impact to spring and Dynamic Friction coefficient is 0.25 Spring Constant is 200 kN/m A) What is the speed...
You pull on a string with a horizontal force F = 34 N that is
attached to a block of mass mb = 7.1 kg, then to the axle of a
solid cylinder of mass mc = 5.7 kg and radius r = 0.4 m, then to a
spring of spring constant k = 115 N/m. This is all done on an
inclined plane where there is friction ( Us = 0.6 and k = 0.30 ), and the incline...
Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
