A 1.0 kg box starts from rest and slides down a very rough inclined plane as shown below. Use energy principles to determine the coefficient of friction on the incline surface if its speed at the bottom is 2.78 m/s. The box sits on a incline that is 0.5m above the ground on a 30 degree incline.
. An aircraft with a mass of 2,000 kg starts from rest at sea level and takes off, then flies to a cruising speed of 620 km/h and altitude of 10 km. Assume g-9.8 m/s throughout the process What is the aircraft's change in potential energy? What is the aircraft's change in kinetic energy? a. b. Answers: About 200 and 30 MJ respectively
a freight plane has a total mass o 4.00 x 10^5 kg (including cargo). It starts from rest at sea level and within 4.00 minutes gets to a speed of 90.0 m/s at a height of 2.00 km. Ignorining the air drag force and friction, what is the averaged required power of its engines?
A 66-kg skier starts from rest at the top of a 1200-m-long trail which drops a total of 180 m from top to bottom. At the bottom, the skier is moving 11 m/s.How much energy was dissipated by friction?
