Hw 1 P 7
Modern wind turbines are larger than they appear, and despite their apparently lazy motion, the speed of the blades tips can be quite high-many times higher than the wind speed. A turbine has blades 51 m long that spin at 14 rpm (Figure 1) Part A At the tip of a blade, what is the speed? Express your answer with the appropriate units. Figure 1 of 1 НА...

Review Constants part. Consider the system of two blocks shown in (Figure 1). The blocks are released from rest. While the two blocks are moving, the tension in the light rope that connects them is 35.0 N. Part 6 If the work-energy theorem is applied to the two blocks considered together as a composite system, use the theorem to find the network done on the system during the 0.900 m downward displacement of the 6.00 kg block. Express your answer...

Please let it be legible, thanks in advance!
You can, in an emergency, start a manual transmission car by putting it in neutral, letting the car roll down a hill to pick up speed, then putting it in gear and quickly letting out the clutch Part A If the car needs to be moving at 3.3 m/s for this to work, how high a hill do you need? (You can ignore friction and drag.) Express your answer with the appropriate...

A Review | Constants Part A A 57.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N, to keep it moving at a steady 25.0 cm/s. What are the coefficient of static and kinetic friction between the crate and the floor? Enter your answers numerically separated by a comma....
