a cartesian diver is a classic science experiment which demonstrates the principle of buoyancy and the ideal gas law.
The kinetic energy of an object is given by
![K= \frac{1}{2} mv^2](https://tex.z-dn.net/?f=K%3D%20%5Cfrac%7B1%7D%7B2%7D%20mv%5E2)
where m is the mass of the object and v its velocity.
For the car in the problem,
![m=1700 kg](https://tex.z-dn.net/?f=m%3D1700%20kg)
and
![v=30 m/s](https://tex.z-dn.net/?f=v%3D30%20m%2Fs)
, so the kinetic energy of the car is
![K= \frac{1}{2}mv^2= \frac{1}{2}(1700 kg)(30 m/s)^2=7.65\cdot 10^5 J](https://tex.z-dn.net/?f=K%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2%3D%20%5Cfrac%7B1%7D%7B2%7D%281700%20kg%29%2830%20m%2Fs%29%5E2%3D7.65%5Ccdot%2010%5E5%20J%20%20)
and as we can see, yes, the answer depends on the car's mass.
True. Classifying by similarities is the basis for biological classification.
Trips/slips/falls are among the most common types of work related injuries and/or deaths.
