Question about solving the air resistance force on a table tennis ball? - air force one tennis shoes
Hello,
Please can you give me some tips on how to resolve this issue:
"A ping-pong of mass 10g is on the ground with a constant speed of 8.2 ms. Calculate the magnitude and direction of the force of air resistance acting to stay on the ball."
I know that obviously the force of air resistance is to act up.
How to solve the actual numeric value of the aerodynamic drag on?
Thank you!

If the ball falls at a constant speed, then it is accelerated.
Because the ball is not accelerating, all the forces acting on it must be zero.
In this case, considering only two forces (1) the gravity it down and (2) the force of air resistance acting upwards.
Thus, the size of the force of air resistance must be equal to the size of the force of gravity. So:
Frequently acceleration of gravity = mass * Fgrav Ball
, 01 kg * 9.8 m / s ^ 2 = 0.098 N
On a perfect day without wind, fall off a cliff, and the time of his fall.
Soon reach terminal velocity.
Calculation of air resistance, dass
