Under Galilean relativity, if a police officer is driving at 50
miles per hour on a highway
with a speed limit of 70 miles per hour, what speed must she
observe from a driver going
in the opposite direction in order to know the person must be
speeding?
Homework Answers
appl6ing concept of relative velocity
over speed limit = actual velocity - person velocity
person velocity = 70 - 50 = 20 miles per hour
========
do comment in case any doubt, will reply for sure.. Goodluck

Speeding Violation Calculator: Design a program that calculates and displays the number of miles per hour over the speed limit that a speeding driver was doing. The program should ask for the speed limit and the driver’s speed. Validate the input as follows: The speed limit should be at least 20 but not greater than 70. The driver’s speed should be at least the value entered for the speed limit (otherwise the driver was not speeding).Once correct data has been...

Consider someone driving down the highway at 70 miles per hour (31.3 m/s). The total mass of the driver and their car (as well as everything else in the car) is 1300kg. A) How much work must friction do to make the car stop? I got −6.37×10^5 J B) A tree suddenly falls on the highway 60m in front of the car, and the driver just barely manages to stop before hitting the tree. What is the magnitude of the...
