Homework Answers
1. A car is mainly designed for the safety of the driver.
2. The front and the rear parts of the car are made of soft metal
so that the car is easily crumpled during an accident.
a) During collision, the time taken for the change in speed (from a
high speed to zero) is prolonged. Since the impulsive force
= Distance / Time , the force will decrease when the time
increase.
Option c is correct one.
b) This will decrease the impulsive force on the passengers and the
driver.
3. The seats of the passengers are strengthened to protect the
passengers.

Contrast and compare elastic and inelastic collisions.
Question 4 options:
Both elastic and inelastic collisions have conservation of
momentum if there are no outside forces. They are different in that
elastic collisions bounce and inelastic collisions stick, and
kinetic energy is conserved in inelastic collisions.
They are basically the same thing, except the units are
different.
Elastic collisions do not have conservation of momentum and
inelastic collisions have conservation of momentum if there are no
outside forces. They are different...

V If two particles of different masses have equal kinetic energy they also have equal momentum. The kinetic energy is always conserved both in elastic collisions and inelastic collisions. If the momentum of a single particle is zero, its kinetic energy may not be zero. The linear momentum of an object is proportional to the mass of the object. A large force always produces a larger impulse on a body than a smaller force. If the kinetic energy of a...
