Bowling ball with air resistance problem

In summary, the conversation discusses the terminal speed of a 22-cm-diameter bowling ball, which is measured at 85m/s. There is confusion about how to find the mass of the ball, but it is suggested to consider the relationships between terminal speed, the size and density of the object, and properties of air. It is also mentioned that for high speed objects, drag force is proportional to the speed squared and the size and shape of the object. The concept of quadratic drag is suggested for further research.

A 22-cm-diameter bowling ball has a terminal speed of 85m/s. What is its mass.

I get F=M(9.8). But then i don't know where to go from there or what to do with the 22 cm diameter :confused:

What relationships do you know between terminal speed and the size and density of an object, and/or properties of air?

nothing, that is the only info givin.

I believe Dan was asking about what you know (or should know) about air drag and what affects it. :smile:

Here's a hint to get you started: For high speed objects traveling through air, the drag force is proportional to the speed squared and depends on the shape of the object (treat the ball as a sphere). Look up quadratic drag.

Edit: The drag also depends on the size of the object; that's where the diameter comes in.

FAQ: Bowling ball with air resistance problem

What is the "Bowling ball with air resistance problem"?

The "Bowling ball with air resistance problem" is a physics problem that involves calculating the motion of a bowling ball as it travels through the air, taking into account the effects of air resistance.

What factors affect the air resistance on a bowling ball?

The air resistance on a bowling ball is affected by the ball's velocity, surface area, and shape, as well as the density and viscosity of the air.

How does air resistance affect the motion of a bowling ball?

Air resistance acts in the opposite direction of the ball's motion, slowing it down. This can cause the ball to deviate from its intended path and decrease in speed over time.

How is the air resistance on a bowling ball calculated?

The air resistance on a bowling ball can be calculated using the drag equation, which takes into account the factors mentioned in question 2. This equation is often solved numerically using computer simulations.

How can air resistance be minimized in bowling?

To minimize air resistance in bowling, one can use a ball with a smooth, polished surface and a streamlined shape. Additionally, throwing the ball with a higher velocity can help reduce the effects of air resistance.
