At the end of the spring term, a high school physics class celebrates by shooting a bundle of exam papers into the town landfill with a homemade catapult. They aim for a point that is 31.1 m away and at the same height from which the catapult releases the bundle. The initial horizontal velocity component is 5.87 m/s.
a) What is the initial velocity component in the vertical direction?
b) What is the launch angle? (in degrees)
