Question

A man of mass 75.5 kg walks down the aisle of an airplane at a speed of 1.50 m/s in the forward direction while the plane moves at a speed of 305 m/s relative to the earth.

(a) Find the man's kinetic energy relative to the plane.


(b) Find the man's kinetic energy relative to the earth.

Answer 1

the speed relative to the plane is 1.50m/s find 1/2 m v^2

the speed relative to the ground is 304.5m/s find 1/2 mv^2

Answer 2

Thanks so much!
