Q1. an airplane is flying horizontally with the speed of 1300km/h while an engine falls off. Neglecting air resistance, suppose it takes 25 s for the engine to hit the ground.

a) what is the altitude of the plane?

b) what is the horizontal distance the airplane engine falls

Q2. An athlete does the 100 m dash. If observers on the spaceship moving with a speed of 0.760c relative to Earth see the athlete's run and measure his time to be 16.34 s, find out the time that was recorded on Earth.
