Q1. A superhero flies 185m from the top of a tall building at an angle of 27 degrees below the horizontal. What is the horizontal component of superhero's displacement?

Q2. Falls resulting in hip fractures are a major cause of injury and even death to the elderly. Typically, hip's speed at impact is about 2. If this can be reduced to 1.30 or less, hip will usually not fracture. One way to do this is by wearing elastic hip pads. What acceleration (in's) does the hip undergo to reduce its speed to 1.30?
