You don’t reach a terminal velocity in such a short distance, but the squirrel does. You know what I'm talking about.Infamous for scurrying about in search of nuts to nibble on, most squirrels are tree dwelling species, and reside at significant heights.But constantly living and scurrying about at heights has its dangers - specifically falling.First we have to understand a bit about falling objects, and the physics behind them.Any falling object has two forces acting on it while it falls.But while the gravitational force is constant throughout it's fall, this drag increases with increase in (the square of) the velocity.So as the velocity increases, there comes a point when the force of drag is equal to the pull of gravity.

That's how you calculate the drag coefficient, which is usually a magic number found based on wind tunnel experiments. I don't think your assumption of the drag coefficient is correct; that is to say, the behavior of the squirrel is more like a piece of paper than a skydiver.I don't think you should model the squirrel as a cube. For a better experience, please enable JavaScript in your browser before proceeding.Let me begin with a fragment quoted from the textbook I'm using: Squirrels (unlike most other mammals) can survive impacts at their terminal velocity. I don't think you should model the squirrel as a cube. Mark Rober 35,667,364 views. Terminal What is the terminal velocity of a squirrel?
Squirrels are pretty small and fluffy. Whereas if the squirrel was shaved than it would fall at a much faster rate and reach a much higher terminal velocity, one that it might not be able to survive. This means that their terminal velocity is actually quite low, and squirrels can survive impacts of that velocity. Terminal velocity doesn't really seem to matter here because the squirrel is nowhere close to reaching it based on the parameters given. However, a small squirrel does this all the time, without getting hurt. I'm sure they could die if they were to nose dive head first into a rock or pavement. Its not that it hits the ground more gently, its that the squirrel's body acts like a parachute and limits its speed to no more than a certain amount and the squirrel can survive any fall at that speed.I think the OP's question stems from the fact that the squirrel's terminal velocity of 24.2 m/s is higher than the velocity it would reach simply falling 5.0 meters. It's usually a function of the surface area with respect to the velocity through the medium. Besides, I didn't propose to model the squirrel as a cube Terminal Velocity Prof. Sachin Jadhav. Hello. No object will fall faster than it's terminal velocity, no matter what height it is dropped from.Professional websites always seem to have a line here.
I don't think you should model the squirrel as a cube. Terminal velocity is the fastest that an object will ever fall, no matter what height it is dropped from. if you drop a pumpkin from a low height it will bounce You don’t reach a terminal velocity in such a short distance, but the squirrel does.##v_t = \sqrt{\frac{2(0.560\ kg)(9.8\ m/s^2)}{(1.0)(1.21\ kg/m^3)(0.0155\ m^2)}}##if you drop a pumpkin from a low height it will bounce Terminal velocity doesn't really seem to matter here because the squirrel is nowhere close to reaching it based on the parameters given.The key difference in terminal velocity is due to the fact that, in general, the volume (and hence the mass and the weight) of an object grows with the third power of the linear dimension, and the area with the square.Drag is very complex; it cannot be modeled by simple kinematic equations.
