Assume that g = 10 N/kg and there is no air resistance . 5 kg
10 kg
1 The rocks above are falling near the Earth's surface.
a What is the weight of each rock?
b What is the acceleration of each rock?
c What is the gravitational field strength?
2) a spacecraft travels from earth to mars where the gravitational field strength near the surface is 3.7 N/kg. The spacecraft is carrying a probe which has a mass of 100 kg when measured on earth. a) what is the probes weight on earth? b) what is the probes mass in space? c) what is the probes mass on mars? d) what is the probes weight on mars? e) when the probe is falling near the surface of mars what is its acceleration?
