Expert Witnesses Use Physics to Analyze Radar Speed Testimony in Court Case

AI Thread Summary
The discussion centers on a court case involving conflicting speed testimonies from a police officer and a driver, with the officer claiming a speed of 176 km/h and the driver asserting he was only traveling at 88 km/h. The possibility of both parties being truthful is questioned, particularly in the context of relative velocity and radar technology. Expert witnesses are needed to analyze the physics behind radar speed measurements, potentially using Doppler radar principles to support their arguments. Visual aids and scripts for both prosecution and defense are suggested to clarify the physics involved. The key inquiry is how relative motion could affect the radar reading, especially if both vehicles were moving toward each other.

i don't know how to solve it so i need for your help to solve the problem below..thanks
There is conflicting testimony in a court case. a police officer claims that his radar monitor indicated that a car was traveling at 176 km/h(110mi/h). The driver argues that the radar must have recorded the relative velocity because he was only going 88 km/h (55 mi/h). Is it possible that both are telling the truth? could one be lying? prepare scripts for expert witnesses, for both the procecution and the defense, that use physics to justify their positions before the jury. create visual aids to be used as evidence to support the different arguments.

thankyou but I'm not learning about doppler formula yet, so i can't use this fomular to solve it...do you have other way to solve? thanks

Suppose the police car and the suspect's car were heading toward each other at 55 mph. What speed would you expect the radar gun in the police car to indicate?
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
