The figure shows three situations in which identical projectiles are launched (at the same level) at identical initial speeds and angles. The projectiles do not land on the same terrain, however. Rank the situations according to the final speeds of the projectiles just before they land, greatest first. If multiple final speeds rank equally, use the same rank for each, then exclude the intermediate ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the ranking would be A:1, B:1, C:3). If all final speeds rank equally, rank each as '1'.

4) A racquetball player encounters a ball coming towards him at a velocity of 22 m/s and at an angle of 5° below the horizontal. He is able to return the ball at a velocity of 30 m/s at an angle of 15° above the horizontal. The 40 gram racquetball is in contact with the racket for 0.04 s. a) Clearly draw coordinate systems for the incoming and outgoing velocity of the racquetball (there should be two). Write out the necessary transformation arrays. b) Draw an FBD of the racquetball. Compute the magnitude of the force exerted by the racquet on the ball. c) Find the angle between the force and horizontal.

A Water Balloon Battle. You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 90 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)?

3. For this series of 5 questions, a block is released from the position shown with a certain initial velocity. It then slides down the smooth (friction-less) path for which the function is given in the image. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 4) If the block has mass of 65 kg and its initial velocity is 2.3 m/s (at x = 3 m), determine the normal force N which the path exerts on the block right before it reaches the spring (at x = 0). Your answer must include 1 place after the decimal point and the proper unit. Take g = 9.81 m/s². k = 5 kN/m puudu Your Answer: Answer units y = 0.25x² 3 m v X
19. You have been hired as an expert witness by an attorney CR for a trial involving a traffic accident. The attorney's client, the plaintiff in this case, was traveling eastbound toward an intersection at 13.0 m/s as measured just before the acci- dent by a roadside speed meter, and as seen by a trustworthy witness. As the plaintiff entered the intersection, his car was struck by a northbound driver, the defendant in this case, driving a car with identical mass to the plaintiff's. The vehicles stuck together after the collision and left parallel skid marks at an angle of 0 ured by accident investigators. The defendant is claiming that he was traveling within the 35-mi/h speed limit. What advice do you give to the attorney? 55.0° north of east, as meas-
Data has been gathered from a lifting system used to remove spent RBMK fuel rods from the spent rod pool into long term safe storage. At present the spent rods are winched up from the pool and then lowered into concrete barrels in a second pool. When it is positioned properly the winch is released and the rod is allowed to drop in. The following calculation is based on data gathered from the present set up. Time taken to lowered into concrete barrels = 10 Seconds Winch drum diameter = 0.9m Mass of load = 185 kg Initial velocity = 0 m/s Distance travelled = 6m You have been asked to use this information to determine: The final linear velocity of the load The linear acceleration of the load The final angular velocity of the drum The angular acceleration of the drum The tension force in the cable The torque applied to the drum In determining the above quantities, you should clearly state the formulae used and apply dimensional analysis techniques to show that all values/units used…
