Plenty of BAD mutations (cancer, Down's Syndrome, etc.), but have there been any that have improved the human race?

I know we had to have some good ones to evolve to where we are, but since we found fire and started writing on walls and made stone weapons, have had any good mutations?

Superball Hits Wall Figure 7-24 shows an approximate plot of force magnitude versus time during the collision of a 60 g Superball with a wall. The initial velocity of the ball is 32 m/s perpendicular to the wall. It rebounds directly back with approximately the same speed, also perpendicular to the wall. What is Fmax, the maximum magnitude of the force on the ball during the collision?

Figure 7-24:

Thanks in advance for any help you can offer!

I know that it was Full Moon just a couple of days ago, so it should still look somewhat circular. Even then, it looked very unusual, not quite circular, almost droopy. What has happened that it looks 'egg-shaped?'

The law of inertia states that no forces is required to maintain motion. Why do we have to keep pedaling the bicycle to maintain motion?

I keep hearing that the US government is retiring its space shuttle fleet in 2010. But I've also heard that President Bush wanted to return people to the moon by 2020, how is that going to happen without space shuttles, and why is the fleet being grounded in the first place?

A student sits at rest on a piano stool that can rotate. The moment of inertia of the student-stool system is 4.1 kg·m2. A second student tosses a 1.5 kg mass with a speed of 2.2 m/s to the student on the stool, who catches it at a distance of 0.37 m from the axis of rotation. The final angular speed is 0.284 rad/s. Calculate the initial and final kinetic energy of the system.
