An empty 15,000-kg cargo truck travels down a flat track at 5.00 m/s. Suddenly, 5,000 kg
of coal are dropped into the truck, directly from the amoeba. Initially, the velocity of the
coal in the horizontal direction is zero with respect to the ground. Find the final speed of
the truck.
Ans. 3.75 m/s.
Internal injuries in vehicular accidents may be due to what is called the “third collision.” The first collision is the vehicle hitting the external object. The second collision is the person hitting something on the inside of the car, such as the dashboard or windshield. This may cause external lacerations. The third collision, possibly the most damaging to the body, is when organs, such as the heart or brain, hit the ribcage, skull, or other confines of the body, bruising the tissues on the leading edge and tearing the organ from its supporting structures on the trailing edge.
a. Why is there a third collision? In other words, why are the organs still moving after the second collision?b. If the vehicle was traveling at 60 mph before the first collision, would the organs be traveling faster than, equal to, or slower than 60 mph just before the third collision?

If you were judging this case, how would you rule and why?arrow_forwardHelparrow_forwardA 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:arrow_forward
