You can perform a popular trick by dropping any peso bill (Ex. 500 peso bill )lengthwise
through the thumb and forefinger of a classmate. Tell your classmate to grab the peso bill as
fast as possible and he/she can keep the money if he/she catches it. The length of the peso
bill is 15.7 cm and the average human reaction time is about 0.20 s. Will your classmate catch
the bill and keep the money?
A red train traveling at 72 km/h and a green train traveling at 144 km/h are headed toward each other along a straight, level track.When they are 950 m apart, each engineer sees the other’s train and applies the brakes.The brakes slow each train at the rate of 1.0 m/s2. Is there a collision? If so, answer yes and give the speed of the red train and the speed of the green train at impact, respectively. If not, answer no and give the separation between the trains when they stop
During a head on collision, the passengers in the front seat of a car accelerate from 13.3m/s to rest in 0.10s. The driver of the car held out their arm to stop their 25kg child from smashing into the dashboard. What force in pounds (1N = 0.225lbs) is needed to keep the child from moving?

- You're driving along at 25m/s with your aunt's valuable antiques in the back of your pickup truck when suddenly you see a giant hole in the road 55 m ahead of you. Fortunately, your foot is right beside the brake and your reaction time is zero! If the coefficients of friction are μs =0.6 and uk =0.3, how much time does it take you to stop if you don't want the antiques to slide and be damaged?arrow_forwardWhile driving to work one day, I was holding my coffee mug in my left hand while changing the radio station with my right hand. Then my cell phone rang, so I placed the mug on the flat part of my dashboard. Then, believe it or not, a deer ran out of the woods and onto the road right in front of me. Fortunately, my reaction time was zero, and I was able to stop from a speed of 17 m/s in a mere 50 m, just barely avoiding the deer, without the coffee mug sliding. The mug (with coffee) had a mass of 550 g, and the mass of the deer was 150 kg. Part A What is the minimum possible value of the coefficient of static friction between the mug and the dashboard?
