Consider a space shuttle which carries life support material from earth to moon. A straight motion with a 384000 km is the closest distance between earth and moon. Assuming the shuttle's acceleration is 20.7 m/s2 for the first time interval 14.6 min of the trip, then travels with a constant velocity until the last time interval 14.6 min , when it accelerates at - 20.7 m/s2 , just coming to rest as it reaches the moon.
a- Find the maximum velocity reached?
b- Which part of the total distance is traveled at constant velocity?
c- How much time needed for the whole trip?
The pilot of the spaceship measures the length of the moving ship as 30 meters. Establish its length as measured by a person on earth.
A jetliner has a gross weight of 250,000 kilogram on its takeoff roll it accelerates from rest to 50 m/s in a distance of 3000 meter. Find the force of thrust of the aircraft's engines
A human cannot hear sound at a frequency of 100 kHz or sound at 102 kHz. But if you walk into a room in which two sources are emitting sound waves, one at 100 kHz and the other at 102 kHz, you'll hear sound. Explain.
