Q1. A superhero flies 287 meters from the top of a tall building at an angle of 17 degrees below the horizontal. What is the vertical component of the superhero's displacement? Answer in units of meters. The horizontal is 274.459 meters and the vertical is.

Q2. A centripetal force apparatus is designed to rotate a 50.0 g mass around a circle with a radius of 25.0 cm. a spring is used to hold the mass at this radius. A force of 2.50N is required to stretch the spring to the correct radius. What is the speed of the 50g mass? What is the angular speed of the mass?
