A marksman fires a practice round from A toward a target B. If the target diameter is 150 mm and the target center is at the same altitude as the end of the rifle barrel, determine the range of "shallow" launch angles for which the round will strike the target. Neglect aerodynamic drag and assume that the round is directed along the vertical centerline of the target. (Note: The word "shallow" indicates a low-flying trajectory for the round.)

Consider again the two wind turbines in Problem 32. a. At what point along the 40-m blade would the angular distance traveled by the point be the same as the angular distance traveled by the point at the end of the 20-m blade? b. At what point along the 40-m blade would the translational distance traveled by the point be the same as the translational distance traveled by the point at the end of the 20-m blade?
A graduate student discovers that the only centrifuge in the laboratory is malfunctioning. The angular speed was supposed to be adjustable, but now it is stuck on a high angular speed, and the student is running an experiment that requires a low translational speed. Fortunately, the arm is adjustable. What can the student do to the length of the arm to get the correct translational speed?

A BMX biker wanted to impress his family by catching some air( aka leaving the ground) while riding over a hill in Tennesse with a radius of curvature of 7.6m. If the BMX biker rides over the hill at 11.2 m/s, will she catch some air and excitee her family? B) What is the minimum speed the biker has to travel in order to leave the ground when cresting the hill?
a. A truck loaded with cannonball watermelons stops suddenly to avoid running over the edge of a washed-out bridge (see figure 1). The quick stop causes a number of melons to fly off the truck. One melon rolls over the edge with an initial speed vi = 14.0 m/s in the horizontal direction. A cross-section of the bank has the shape of the bottom half of a parabola, with its vertex at the initial location of the projected watermelon and with the equation y2 = 12x, where x and y are measured in meters. What are the x and y coordinates of the melon when it splatters on the bank? b. From the relationship between the launch angle ?, and the horizontal range R, for a dart launched with a speed v. This assumed that the launcher and the target were on the same horizontal level. Relax this assumption and place the launcher at some elevation h above the target, as in figure 2. i. Derive the symbolic equation relating the range R, to the launch angle ?, launch speed v, launcher elevation h, and…

A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory isturned off, it continues to rotate with a constant angular deceleration for 10.2 s before coming to rest. (a) If its initial angular speedwas 3850 rpm, what is the magnitude of its angular acceleration?(b) How many revolutions did the centrifuge complete after beingturned off?
