A marksman fires a practice round from A toward a target B. If the target diameter is 170 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.)

A medium size catapult launches 8-lb steel spheres. The launch speed is the launch angle is above the horizontal, the launch position is 6ft above ground level. An athletic field is used with an adjoining slope topped by an 8ft fence as shown. Determine: (a) the x-y coordinates of the point of first impact (b) the time duration of the flight (c) the maximum height h above the horizontal field attained by the ball (d) the velocity (expressed as a vector) with which the projectile strikes the ground
In the selection of the ram of a pile driver, it is desired that the ram lose all of its kinetic energy at each blow. Hence, the velocity of the ram is zero immediately after impact. The mass of each pile to be driven is 340 kg, and experience has shown that a coefficient of restitution of O.25 can be expected. What should be the mass m of the ram? Compute the velocity v of the pile immediately after impact if the ram is dropped from a height of 3.3m onto the pile. Also compute the energy loss AE due to impact at each blow. 3.3 m 2.2 m Answers: m = i kg V = i m/s ΔΕ Ξ i

An electric motor M is used to reel in cable and hoist a bicycle into the ceiling space of a garage. Pulleys are fastened to the bicycle frame with hooks at locations A and B, and the motor can reel in cable at a steady rate of 20 in./sec. At this rate, how long will it take to hoist the bicycle 7.9 feet into the air? Assume that the bicycle remains level.
