The force F exerted by the wind on a window varies jointly with the area A of the window and the square of the velocity of the wind. If the force on a window of 25 square feet is 20 pounds when the wind velocity is 4 mph, find the force on a window of 22 square feet when the wind velocity is 5 mph.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Your bicycle has 10 gears, from low (easiest to pedal) to high (hardest to pedal). When you first start peddling, you usually use a low gear to accelerate from standing and then shift to a higher gear when you are at a high cruising (ground) speed so that you are always pedalling against the same resistance. One morning you forget to shift down and you try to start in a very high gear. Despite the fact that you usually go fast in high gear, you can't get anywhere at all. The next day you remember to start in low gear, but you forget to shift up. So you ride to school at the same ground speed as usual but in low gear all the way. Despite the fact that there is less resistance to pedalling in the low gear, your legs get more tired than usual. Using you knowledge of force and resistance explain why they are more tired? Explain which skeletal fibers will be utilized in this case?
Figure 7.7 shows a power hacksaw. At this instant, the electric motor rotates counterclockwise and drives the freeend of the motor crank (point B) at a velocity of 12 in./s. Additionally, the crank is accelerating at a rate of 37 rad/s^2. The top portion of the hacksaw is moving toward the left with a velocity of 9.8 in./s and is accelerating at a rate of 82 in./s^2. Determine the relative acceleration of point C with respect to point B.

A shaft 5.0 cm in diameter and rotating at 2,400 rpm, comes to a full stop in 6.0 seconds. It slows down to 1200 rpm during the first 2.0 seconds and comes to a full stop at the end of the sixth second. The acceleration is constant during both segments of the motion. Determine: a.The total number of turns it completes during the 6.0 seconds it is slowing down, b.the distance traveled by a point on the rim of the shaft during this time, and c.the average acceleration during the first 2.0 seconds in rad/s2.
