Cars these days have parts that can crumple or collapse in the event of an accident. What is the advantage of this? Now choose from one of the following optionsWhy?
a It reduces injury to the passengers by increasing the time of impact.
b It reduces injury to the passengers by decreasing the time of impact.
c It reduces injury to the passengers by increasing the change in momentum.
d It reduces injury to the passengers by decreasing the change in momentum.
Homework Answers
The time taken in collapsing of the parts increases the time of
collision. Since the force is rate of change of momentum, the
impact force decreases reducing injury to the passengers.

Police Report: There were two individuals involved in the accident. No other passengers were present and no other vehicles were involved. There was a truck of mass 1,936 kg traveling Southbound on H and a compact car of mass 1,077 kg travelling Northbound on HWY 26. A bystander claims to have watched the vehicles collide and slide Southbound off the road into a tall grassy ditch. The grass was determined to have a coeficient of friction of 0.6, while the...

There was a car accident. Someone stopped and the person
behind them rear ended them. The car that stopped slid away about
30 feet and the car that did the rear ending stopped right about
where the collision happened. Was this a perfectly inelastic
collision? Why or why not?
A perfectly elastic collision is one in which kinetic
energy is conserved. How exactly is kinetic energy not conserved
though? Sometime KE can be used up compressing/bending things and
making heat,...

A small rural bridge will have, at most, two cars on it at a
time. Assume it can be modeled as a rigid horizontal beam element
supported by three elastic vertical columns as shown.
Your design condition is two cars each weighing P=40kN
each travelling exactly 20m apart from each other across the
bridge. Find the maximum compressive and tensile forces experienced
by the columns. For now, you can assume the maximum forces will be
experienced when both cars are...

Let the random variable T be the time until some event occurs (e.g. time until an atom decays, time until next rainfall, etc). Suppose it’s a continuous random variable supported on [0, ∞). The hazard rate for T is defined as h(t) = f(t) 1 − F(t) , where f and F are the density and CDF for the distribution of T. On an intuitive level, this is the chance that the event will occur in the very near future,...

The international airport in Brezuela, a vibrant city in the country of Bonitas, auctions an exclusive license every year to a taxi company for the right to serve the airport's passengers. Victor Diego is the owner of Speedy Motors, the taxi company that won this year's license. Currently, with average revenue at $2 per mile, Speedy Motors earns marginal revenue of $1 per mile. Since there are no other taxis available at the airport, Victor feels that they can increase...

Imagine you and your friends have created a new prototype of an electric car and you are discussing the possibility of opening a start-up to produce and sell it. Your big shot is represented by the US! Even though it is still a market niche, US electric car demand is high enough to allow you high returns to your investments. To this extent, you start gathering information to be able to draw a production plan. Yet, there is a big...
