You are a police officer examining the scene of a car crash that claimed the life of someone driving a Tesla. There was a collision involving them and a pickup truck. The truck driver, who survived, said he was travelling North into the intersection and the Tesla was travelling East into the intersection. The truck driver claims that he was not exceeding the speed limit when the accident occurred. You note the posted speed limit was 80 km/h. Like airplanes, Teslas have a black box that records various statistics in the event a collision occurs. After analyzing the data from the black box, you discover the Tesla was driving at a velocity of 69.8 km/h [E] when the collision occurred. You google the mass of both of the vehicles and find the Tesla should be about 2240 kg and the truck should be about 2930 kg. During the collision, the two vehicles crumpled and became entangled, the skid marks revealing that the two vehicles travelled E 57 N after impact. How fast, in km/h, was the truck actually driving at the moment of impact? W L 0 You are a police officer examining the scene of a car crash that claimed the life of someone driving a Tesla.

Answer rating: 100% (QA)

The scenario described involves a collision at an intersection between a Tesla and a pickup truck To solve for the trucks speed at the moment of impact we can use the conservation of momentum which st... View the full answer
