Explanation The car is connected to the trailer; hence, both the car and the trailer have the same acceleration. The force exerted by the car on the trailer can be calculated using the formulae for the force of friction and Newton’s second law. Given: The mass of the car m c = 1280 kg Mass of the trailer m t = 350 kg Force exerted by the car on the ground F c = 3.6 × 10 3 N Formula used: F f r = μ k m t g a = F c − F f r m t + m c F = F f r + m t a Calculation: The trailer has a coefficient of kinetic friction μ k between itself and the ground. Calculate the force of friction. F fr =μ k m t g =(0.15)(350 kg)(9.8 m/s 2 ) =514.5 N The car exerts a force F c on the ground. The force of friction acts in the opposite direction to it...

While cruising down University Boulevard you are stopped by a cop who states that you ran a red traffic light. Because you don't want to pay the stiff fine, you are attempting a physics defense. You claim that due to the relativistic Doppler effect, the red color of the light λ=616 nm appeared green '=531 nm to you. The cop makes a quick calculation of his own and rejects your defense. How fast, in terms of your speed u divided by the speed of light in vacuum c, would you have to drive to justify your claim? Note that the speed u is taken to be a positive quantity. U 4.0 C
