Question #91871
1 Answer
(a) The given slope is
i.e.,
When the car rolls down
we get
Loss of Potential energy of the automobile
This gets converted in kinetic energy of the automobile
where
Equating the two we get
In the given elastic collision both momentum and kinetic energy are conserved. Assuming that both automobiles move in the same direction down hill we get from momentum
where
from Kinetic energy we get
Solve equations (3) and (4) for
