You’re using a wedge to split a log. You are hitting the wedge with a large hammer to drive it into the log. It takes a force of 2000 N to push the wedge into the wood. If the wedge moves 0.2 into the log, how much work have you done on the wedge?
A jet transport with a landing speed of 200 km/h reduces its speed to 60 km/h with a negative thrust R from its jet thrust reversers in a distance of 425 m along the runway with a constant deceleration. The total mass of the aircraft is 140 Mg with mass center at G. Compute the reaction N under the nose wheel B toward the end of the braking interval and prior to the application of mechanical braking. At the lower speed aerodynamic forces on the aircraft are small and may be neglected.

The movie Interstellar is based on the premise of trying to find another habitable planet after ours has become inhabitable. From the knowledge you have gained from this class, discuss the following:
· What aspects of this new planet would you look for to ensure the survivability of our species? Some of the specifics you may want to discuss are:
Size and age of the planet
Atmosphere of the planet
The distance of the planet to its Sun
The type of Sun the planet orbits
Oceans of the planet
Any life that may already be on this planet
Moons of this planet
