Mass of the plane = m = 830 kg
Initial speed of the plane = V1 = 0 m/s
Final speed of the plane = V2 = 10.8 m/s
Length of the runway = L = 1.5 km = 1500 m
Time period of acceleration = T = 4.53 min = 4.53 x (60) sec = 271.8 sec
Total work done on the plane = W
The change in kinetic energy of the plane is equal to the total work done on the plane.
W = 4.8 x 104 J
Total work done on the plane = 4.8 x 104 J

A plane takes off and climbs to 3 000 m in five minutes at an angle of 8.28 degrees. When it reaches 3 000 m, the plane levels out and adjusts to its constant cruising speed of 500 km/h. At this height, there is a wind (a "jet stream") blowing at 100 km/h 30 degrees East of North. a) What is the magnitude of the plane's acceleration during the first five minutes of the flight? b) After reaching its cruising...

1) A cart for hauling ore out of a gold mine has a mass of 447 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.63∘ incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 436 N force for a distance of 115 m by means of a rope that is parallel to the...
