A 200g ball thrown vertically upwards at a speed of 25m / s reaches a height of 22. Calculate the loss of energy due to the resistance of the air. What is the average strength of the air resistance

Respuesta :

Without air resistance, the ball would reach a height of h = 31.9 m(pic 1)
The gravitational potential energy difference would be ΔU = 62.588J - 43.164J = 19,424J (pic2 + 3)
The work done by air resistance must be equal to the energy difference(pic4)
The magnitude of the air resistance: F = 0.883N
