Figure 2-28 shows a red car and a green car that move toward each other. Figure 2-29 is a graph of their motion, ; showing the positions xg0 : 270 m and xr0= -35.0 m at time t = 0. The green car has a constant speed of 20.0 m/s and the red car begins from rest. What is the acceleration magnitude of the red car?
A uniform solid disk of mass m = 3.01 kg and radius r = 0.200 m rotates about a fixed axis perpendicular to its face with angular frequency 5.96 rad/s. Calculate the magnitude of the angular momentum of the disk
The diagram above shows three different fuids that have been added to a glass U-tube that is open to the air. The fuids are in equilibrium and do not mix. Let the fuid on the left have a density of 1000 kg m3 and the fuid on the bottom have a dens..
