Q1. A rookie quarterback throws a football with an initial upward velocity component of 15.33 and a horizontal velocity component of 20.4. Overlook air resistance.

Q2. A bell at a railway crossing sounds with frequency of 800 Hz. Imagine the speed of sound in air on this day is 325 m s-1. The bell is fixed and an observer is moving away from the bell on a train carriage at a speed of 50.0 m s-1 relative to the bell.

Will the observed pitch be higher or lower than emitted pitch?
