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 69.6 km/h [E] when the collision occurred. You google the mass of both of the vehicles and find the Tesla should be about 2020 kg and the truck should be about 2820 kg. During the collision, the two vehicles crumpled and became entangled, the skid marks revealing that the two vehicles travelled E 68° N after impact. How fast, in km/h, was the truck actually driving at the moment of impact?

Concept explainers

Displacement, Velocity and Acceleration

In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.

Linear Displacement

The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

Question

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 69.6 km/h
[E] when the collision occurred. You google the mass of both of the vehicles and
find the Tesla should be about 2020 kg and the truck should be about 2820 kg.
During the collision, the two vehicles crumpled and became entangled, the skid
marks revealing that the two vehicles travelled E 68° N after impact. How fast, in
km/h, was the truck actually driving at the moment of impact?

You are working part-time for the GT Sports Media Complex, editing video for the women’s softball team. In one particular clip, a GT player hits a home run over the center field fence. The ball leaves the bat at a height of 4 ft, and crosses the outfield fence (220 ft away) at a height of 10 ft. Logs of the game indicate that the pitch was clocked at 68 mph as it reached the plate. Your frame-by-frame analysis of the 30-frame-per-second video indicate that the ball spent only a single frame in contact with tha bat, and another 126 frames travelling to the outfield fence. A quick internet seach tells you that a typical college softball weighs 0.4 lb. How many pounds of average force act on the ball during ocntact with the bat?

Archibald, an aging geezer, is out bicycling one fine afternoon, reliving his glorious youth and oblivious to the world around him. As he approaches a busy intersection, a police officer directing traffic blows his whistle to get Archie’s attention so he’ll slow down and stop. But Archie doesn’t stop; he just speeds right through the intersection as if the traffic cop wasn’t even there. The cop radios one of his colleagues and gets her to stop the old geezer. She gives him a traffic citation for failing to heed the command of a police officer directing traffic. When the case gets to traffic court, Archie explains to the judge that he didn’t hear the officer’s whistle because he is going deaf and cannot hear frequencies above 3000 Hz. The traffic cop informs the judge that his standard issue police whistle emits a frequency of 2100 Hz and he has a certificate to prove it. Thinking quickly (at least for an old geezer) Archie says that it may be true that the police whistle emits a sound…
Cities A and B are connected by a straight road of total length 200 miles.Two cars depart cities A and B at the same time, moving towards each other. The A-car travels at 60 miles per hour, and the B-car at 40 mph. At the same time, a fly starts off from the front bumper of the A-car flying at 100 mph. It flies towards city B until it touches the bumper of the B-car, and then flies back, touches the A-car, flies back, etc, until the cars collide and the fly is squashed. The standard trick question is - what is the total distance traveled by the fly? At first sight one would think that the problem should be solved by the series summation, but that’s not necessary - the cars meet after 2 hours, and during that time the fly traveling at 100 mph covers exactly 200 miles. Now that you know the answer, solve this problem using the series summation [1].
