What do we mean by gravitational time dilation?
a) it is the idea that time runs slower in places where gravity is stronger. b) it is the idea that clocks run slow for people moving at high speed past you. c) it is the idea that everyone measures time differently, depending on his/her reference frame. d) it is the idea that clocks run faster in stronger gravitational fields.

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.
