- School bus drivers are extra careful when they cross railroad tracks. They stop before they cross railroad tracks to be sure that there is no train coming. Yet, trains typically move more slowly through towns than cars do. If trains usually move more slowly than cars, why can they do more damage if they hit something in their path?A passenger sitting in the rear of a bus claims that she was injured as the driver slammed on the brakes, causing a suitcase to come flying towards her from the front of the bus. If you were judging this case, how would you rule and why?If a 140 g baseball strikes your head at 33 m/s and stops in 0.0014 s , what is the magnitude of the ball's deceleration.
- A biomechanics forensics expert is attempting to determine the events that led to an automobile accident in which one car rear-ended another. The two cars were originally travelling in the same direction. Car A was traveling at a speed of 42 km/hr when it was struck by Car B, which was traveling at 65 km/hr. Following the collision, the two cars became entangled and continued to travel as one unit with a speed of 53 km/hr. From an interview with the driver of Car A, the forensics expert learned that the mass of Car A is 575 kg. What is the mass of Car B (in kg)? Express your answer in kilograms to one decimal place (do not include units in your answer). Your Answer:A 1000 kg car collides with a 1 mg mosquito. By what factor will the acceleration of the mosquito be greater than the acceleration of the car when they collide?A 1500 kg car traveling at 12 m/s suddenly runs out of gas while approaching the valley shown in the figure. The alert driver immediately puts the car in neutral so that it will roll. What will be the car’s speed as it coasts into the gas station on the other side of the valley?
- In 1896 in Waco,Texas,William Crush parked two locomotives at opposite ends of a 6.4-km-long track, fired them up, tied their throttles open, and then allowed them to crash head-on at full speed in front of 30,000 spectators. Hundreds of people were hurt by flying debris; several were killed. Assuming each locomotive weighed 1.2 * 106 N and its acceleration was a constant 0.26 m/s2, what was the total kinetic energy of the two locomotives just before the collision?Some people say that the “force of inertia” (or “force of momentum”) throws the passengers forward when a car brakes sharply. What is wrong with this explanation?Lionel Messi scores a last second goal and, in celebration, runs as fast as he can, drops to his knees and slides along the wet grass of the field. Messi has been clocked (this is true) at a top speed of 9 meters per second in a game. Let's take this as his maximum velocity and the speed he is moving right before he drops down to slide.Take Messi's mass to be 72 kilograms, and take the coefficient of kinetic friction between skin and wet grass to be 0.4How far does Messi slide?
- A car (mass 1000 kg) is traveling at 60 mph (26.82 m/s) when the driver notices a cat 50 m ahead in the road. Wanting to save the feline's life, the driver slams on the brakes and comes to a stop 2 m in front of the cat. What was the car's acceleration as it was braking?In the movie The Rocketeer, a teenager discovers a jet-powered backpack in an old barn. The backpack allows him to fly at incredible speeds. In one scene, however, he uses the backpack to rapidly accelerate an old pickup truck that is being chased by “bad guys.” He does this by bracing his arms against the cab of the pickup and firing the backpack, giving the truck the acceleration of a drag racer. Is the physics of this scene “Good,”“Bad,” or “Ugly?” Draw and Explain.While 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? Hg =
