In an inelastic collision involving an isolated system, the final total momentum is
Aleksandr-060686 [28]

Answer: B) exactly the same as the initial momentum.

Explanation:

An inelastic collision occurs when the elements that collide remain together after the collision, and althogh the kinetic energy is not conserved because is transformed into other kinds of energy (thermal energy, for example), the linear momentum does.  

This means the initial momentum before the collision will be equal to the final momentum after the collision:

p_{o}=p_{f}

Explanation:

At a height of 93 m, the gravitational potential energy is given by :

P = mgh

Where, m is the mass of a penny

We can find its mass.

m=\dfrac{P}{gh}\\\\m=\dfrac{3}{9.8\times 93}\\\\m=0.00329\ kg

We need to find how much potential energy will have transformed into kinetic energy at the half way point (46.5m). It can be calculated as :

E=mgh'\\\\E=0.00329\times 9.8\times 46.5\\\\E=1.499\ J

Hence, a penny will have transferred 1.499 J of potential energy into kinetic energy.
