Gravitational Potential Energy and Kinetic Energy problem 9


A body weighing 100 g thrown vertically upwards at a speed of 10 m/s falls back to the ground at a speed of 7.5 m/s.


  • How much work does the force of air resistance do?

  • How high does the body fly if we take into account the air resistance?

  • How high does the body fly if the air resistance is ignored?
