An astrophysics researcher is conducting a laboratory simulation to investigate the dynamics of a prototype planetary lander on a low-friction horizontal table.
State the equation that relates the net force F F\,F acting on an object, its mass mmm, and its acceleration aaa.
In one experimental trial, a net force of 0.748 N is applied to the lander, which has a total mass of 1.60 kg. Calculate the acceleration of the lander during this trial, giving your answer to 3 significant figures.
The researcher conducts multiple trials but observes slight variations in the recorded acceleration due to environmental fluctuations. Suggest how the researcher can reduce the impact of these random errors to obtain a more reliable value for the acceleration.
